House Party Walkthrough: Route Order, Key Items, and Achievement Cleanup

Route planning, key items, character locks, DLC order, and achievement cleanup

House Party is not a normal linear adventure. It is a branching party sim where nearly every character has an opportunity chain, several chains borrow the same items, and one careless choice can close a route for the rest of the save. This guide is written for players who want a practical route through the Original Story and achievement cleanup without copying a giant line-by-line script into the article.

The short version: make a clean setup save, learn where the house’s reusable items are, then split your run into branches. Trying to force every romance, prank, fight, DLC guest, and achievement into one unplanned save is where most failed runs begin.

Best Article Type For This Game#

This is best approached as a walkthrough and achievement cleanup guide, not a strict step-by-step script. The readable references support detailed routes for Madison, Leah, Amy, Ashley, Brittney, Derek, Frank, Katherine, Patrick, Rachael, Stephanie, Vickie, Liz Katz, Doja Cat, Lety, Game Grumps content, Nocturnal Temptations, item locations, combat perks, controls, and achievements. Because the game is heavily adult-themed, this public guide focuses on route structure, flags, items, and achievements while avoiding explicit scene descriptions.

Before You Start#

Use these rules before you chase any long chain:

• Save manually and name branches. Quick save is useful, but named saves are safer because many decisions have delayed consequences.
• Do not steal in front of Derek, Madison, or Frank. Several important items are in watched rooms, and getting caught can collapse a route or trigger a fight.
• Talk to everyone once early. The Social Butterfly achievement and several introduction gates depend on meeting the starting cast.
• Let the early random events happen. Rachael confronting Patrick and Amy hurting her toe open useful relationship and dialogue options.
• Check the Opportunities menu often. If a route seems stuck, the menu usually tells you which person, item, or location is still missing.
• Keep adult-content settings consistent. Some community routes assume the explicit version. If your menu/options differ, use this guide’s route logic rather than expecting every scene prompt to match.
• Do DLC in planned blocks. Liz, Doja Cat, Lety, Game Grumps, Date Night with Brittney, and Nocturnal Temptations can change who is available and what the front door is doing.

Clean Setup Save#

Create this save before committing to any character route. It saves a lot of repetition and gives you a stable base for achievement branches.

1. Start the Original Story.
2. Introduce yourself to Madison, Brittney, Amy, Ashley, Katherine, Rachael, Stephanie, Frank, Patrick, Derek, and Leah.
3. Speak politely unless you are intentionally going for a negative reaction achievement.
4. Watch the early Rachael/Patrick and Amy/Stephanie incidents if they occur nearby.
5. Pick up only low-risk items while no one is watching. Leave theft-sensitive items for route-specific branches.
6. Open the Opportunities menu and confirm your first route target.
7. Save as Clean Setup.

From here, make separate saves for Madison, Ashley, Amy, Leah, Patrick/Rachael, combat, DLC guest chains, and achievement cleanup. You can complete many paths in one long run, but the safest completion route is a hub-and-branch structure.

Save Branch Plan#

The most useful save points are not random. Put them before a character lock, a front-door invite, a major fight, or a mutually exclusive choice.

Save name	Make it when…	Why it matters
Clean Setup	Everyone is introduced and early incidents have happened.	Reusable start for almost every route.
Madison Choice	You can pursue Madison’s art route or prank route.	Some Madison choices can lock Derek/Ashley outcomes.
Amy Hunt	Amy’s scavenger chain has begun.	Lets you split between finishing the hunt and alternate outcomes.
Patrick/Rachael	You are handling Patrick’s phone, Rachael’s thermos, or Frank’s liquor control.	This cluster affects Vickie, Katherine, Compubrah, and several achievements.
Combat Prep	You are about to challenge Frank or trigger a fight achievement.	Combat perks and backup helpers can decide success or a reload.
Front Door Queue	Before opening the door for Liz or another invite-only guest.	Only one door event can be active cleanly; guest timing matters.
DLC Finale	Before Nocturnal Temptations or Doja Cat end choices.	Lets you collect multiple ending/achievement outcomes without replaying the whole DLC.

Key Items You Should Know First#

Most routes are not hard because of dialogue; they are hard because an item is watched, situational, hidden behind furniture, or required by several characters. These are the items to learn early.

Item	Usual location	Main use	Risk note
Madison’s expired credit card	Desk drawer in the front room / computer area	Amy’s scavenger route	Take it only when nearby guests are not watching.
Rachel’s thermos	Liquor cabinet area	Rachael/Frank/Patrick routes	Frank’s trust and liquor rules are tied to this cluster.
Skeleton key	Garage shelf near the workbench	Bathroom locks and privacy routing	Critical for routes that require controlling room access.
Mysterious key	Living room mantle	Master bedroom lock	One of the most important keys for private-route branches.
Madison’s phone	Master bathroom sink	Madison route and related opportunities	Do not parade stolen items in front of their owner.
Madison’s diary	Safe in the master closet	Madison/Ashley prank logic	Wait until Madison is away or lock her out.
Paper and pencil	Study/office and spare bedroom	Petition, notes, and several puzzle-like steps	Small items are easy to miss on desks and shelves.
Whipped cream	Fridge	Stephanie route	Move food in the fridge if you cannot see it.
Chardonnay	Laundry room closet	Stephanie route	Useful in several party-escalation paths.
Camera	Master bedroom vanity	Madison, DLC, and evidence-style tasks	Often pairs with the SD card from the study.
Speaker and broom	Living room and art-room closet	Hot tub / backyard setup, DLC staging	Derek or Madison may react if they see you taking the speaker.
Compubrah briefcase	Gazebo roof	Patrick/Lety/Nocturnal Temptations routes	Requires setup or object handling to retrieve safely.

Recommended Route Order#

There is no single official order, but this route keeps dependencies manageable and avoids the most common locks.

1. Learn the house and finish simple social achievements

From Clean Setup, meet every starting guest and inspect at least 30 objects for Inspector. Do not rush into pranks, fights, or adult-scene achievements. Your goal is to understand where rooms connect: front room, living room, kitchen, garage, lower bathroom, backyard, master bedroom, art room, study, laundry room, upper bathroom, and spare bedroom.

2. Build the Madison/Ashley/Derek branch

Madison is the host and many routes reference her room, art, phone, diary, and relationship with Derek and Ashley. Save before choosing whether to help Madison with an art route, prank Ashley, or keep Derek’s route clean. If you want both Madison-focused achievements and Derek friendship outcomes, use separate saves.

Risk: Madison routes can affect Ashley and Derek. If you are chasing The Muse: Madison, The Muse: Derek, Host Hijinks, or Hijinks Averted, do not overwrite your pre-choice save.

3. Start Amy’s scavenger route early

Amy’s path is a good backbone because it pushes you to gather several house-wide items: credit card, a protection item from Frank, Derek’s shirt, paper/petition steps, and later cross-route requirements. It teaches the core game pattern: learn what a character wants, solve a small social puzzle, then use another guest to unlock the next item.

Risk: Amy can lose interest if she catches the wrong branch outcome. Save before moving her route into any romance-heavy or hot tub-related choice.

4. Use Stephanie and Brittney as the party-escalation branch

Stephanie’s route uses kitchen, fridge, wine, thermostat, and dancing-related triggers. Brittney’s route depends on shirt/help logic and can split into A Friend in Need…, Love Conquers All, The Crush, and The Crush(es). Keep a save before choosing whether Brittney’s route stays solo, points toward Amy, or moves into a combined branch.

5. Resolve Patrick/Rachael/Frank carefully

This is the most interconnected cluster in the Original Story. Patrick’s alcohol, phone, Rachael’s thermos, Frank’s control of the liquor cabinet, Katherine’s tech help, and later Vickie/Compubrah logic all touch this cluster. If you plan to complete The Brahdyssey, Relentless, Benedict Brahrnold, A Striking Resemblance, or Compubrah-related achievements, make a branch save before you turn Frank or Patrick against each other.

6. Do combat only after preparation

House Party combat is intentionally clumsy if you ignore stat boosts. Before fighting Frank or chasing combat achievements, collect safe performance boosts: run often, use food for recovery, practice beer pong for speed, climb the gutter, punch the bike lock or katana when appropriate, reach for the MP3 player, and use route-based stamina boosts only if they are already compatible with your save.

Risk: Some combat achievements require very specific behavior. Keep a Combat Prep save and do not mix it with delicate friendship routes.

7. Bring in DLC and invite-only guests last

Invite-only or DLC guests are best handled after the Original Story branch you care about is stable. Liz Katz’s mystery, Doja Cat’s event chain, Lety, Game Grumps, Date Night with Brittney, and Nocturnal Temptations all add timing, front-door, item, or character availability concerns.

Important: If Liz is waiting at the front door, other door arrivals may be delayed. Plan one guest event at a time.

Character Route Notes#

Use this table as a route planner before opening a full line-by-line walkthrough.

Character / content	Main route idea	Save warning
Madison	Host route involving art, her room, phone, and Ashley/Derek tension.	Branch before choosing Madison over Derek/Ashley outcomes.
Ashley	Prank/reconciliation route with clothing, apology, and trust flags.	Madison prank choices can close cleaner Ashley outcomes.
Amy	Scavenger Hunt route that teaches item chains.	Branch before finishing or bailing on the hunt.
Brittney	Shirt/help route that can later split toward personal or crush outcomes.	Do not ignore her too long after setup.
Derek	Friendship, memory, job, and Madison-related choices.	Madison intimacy/prank choices can affect Derek route options.
Frank	Liquor guardian, fight target, and several unusual achievement paths.	Combat and Frank-friendly endings conflict; save before violence.
Katherine	Tech help, phone/text logic, and personal route.	Often needed as utility even if she is not your main target.
Leah	Light/dark route split with training, serpent, and Ronin/Bride outcomes.	Save before committing to her moral route.
Patrick	Backstory, phone, alcohol, Compubrah, and chaos routes.	Several achievements require either helping or exploiting him.
Rachael	Thermos, Patrick drama, and phone-message routes.	Do not lose track of Frank’s liquor rules.
Stephanie	Party/dance route using whipped cream, wine, temperature, and cash.	Her route often feeds Ashley/Vickie or party escalation.
Vickie	Invite through app logic, training, and hot tub branch.	Requires other routes and endurance/combat setup to go smoothly.
Liz Katz DLC	Murder mystery route with clues, vents, trunk, breaker, and final deduction.	Start on a clean branch; Patrick availability changes during the mystery.
Doja Cat DLC	Neighbor invite, backyard production setup, crew management, and event finale.	Keep a save before the final show and guest-management steps.
Nocturnal Temptations	Time-travel film route involving Compubrah, Vickie, Madison, Patrick, Gisella, and Babs.	Use multiple saves near the finale for alternate achievement outcomes.

DLC And Extra Story Order#

Readable sources confirm the menu can include the Original Story plus official story options such as A Vickie Vixen Valentine, Combat Training, and Date Night with Brittney, along with custom stories. Steam metadata also lists multiple DLC app IDs. For cleanup, handle extra content in this order:

1. Combat Training / performance prep: Use this knowledge before Frank-heavy achievements.
2. A Vickie Vixen Valentine: Good to separate from Original Story saves because it is a themed route.
3. Date Night with Brittney: Keep it separate from Brittney’s Original Story branches.
4. Liz Katz mystery: Do after Original Story cleanup if you need Patrick available for other routes.
5. Doja Cat event: Do as a dedicated branch because it uses many guests as crew.
6. Nocturnal Temptations: Do late, with several finale saves for alternate achievements.

Achievement Cleanup Strategy#

Steam lists 91 achievements for House Party. Do not chase them alphabetically. Group them by the kind of save they require.

Achievement group	Examples	Best cleanup method
Intro and general	Social Butterfly, Inspector, The Brahdyssey	Do early from Clean Setup before routes get messy.
Character completion	Amy, Ashley, Katherine, Rachael, Stephanie, Vickie	Use one named save per character cluster.
Smooth Operator / alternate paths	Smooth Operator: Madison, Smooth Operator: Ashley	Branch before full route completion because these can bypass normal story endings.
Friendship / wholesome branches	The Muse: Derek, Hijinks Averted, Good Ol’ Days	Do on saves where you have not burned Derek or Madison trust.
Conflict and combat	Relentless, Duck n’ Weave, Sucker Punch, The Harder They Fall…Dood	Prepare perks, save, then treat them as disposable branches.
Patrick / Rachael / Compubrah	Benedict Brahrnold, A Striking Resemblance, The Elder Brahs, It’s an Older Code…	Keep Patrick’s phone, Rachael’s thermos, and Compubrah logic organized.
DLC achievements	Elementary, My Dear Player; It Smells Like Roses; Nocturnal Temptations	Do each DLC on its own branch with a save before the finale.
Failure / bad-outcome achievements	Ice Bath, Party Pooper, Congrats, A Celebrity Hates You	Use throwaway saves so negative reputation does not poison real routes.

If an achievement pops in-game but does not show on Steam immediately, exit to Steam and refresh before assuming it failed. One readable achievement guide specifically notes delayed Steam-side updates for some unlocks.

Combat And Performance Perks#

You rarely need to fight well unless you are chasing Frank/Derek/Patrick achievements, but it helps to know the stat boosts. Verified community notes list these useful preparations:

• Run often to improve speed over time.
• Use painkillers carefully for stamina-related benefits; do not burn them too early if a route needs them as an item.
• Practice beer pong in the garage for combat speed.
• Climb the gutter for a strength-related boost.
• Punch the bike lock or katana only if it does not interfere with your current route.
• Use fridge food and soda as practical combat recovery.
• Bring backup through Derek/Patrick route logic before fighting Frank when the achievement allows it.

The safe advice is simple: do non-combat story routes first, then load a combat branch and make a mess there.

Common Route Mistakes#

• Overwriting the only clean save. This is the biggest 100% killer. Keep Clean Setup untouched.
• Starting DLC while a base-game dependency is unfinished. Liz, Doja Cat, Lety, and Nocturnal Temptations can change timing and availability.
• Assuming a missing prompt is random. It is usually a missing item, relationship score, clothing state, room lock, or character position.
• Taking watched items too early. The credit card, phone, diary, speaker, alcohol, and some keys should be taken with room awareness.
• Mixing fight achievements with romance/friendship saves. A fight branch should be disposable unless the route explicitly needs it.
• Using console commands before achievements. Community control guides note that many modifying commands can disable achievements for the current save.
• Forgetting gender-specific branches. Some routes and achievements behave differently depending on player character selection.

Quick Cleanup Checklist#

Before you call a run finished, check these items:

• Met every starting guest for Social Butterfly.
• Inspected enough objects for Inspector.
• Finished your chosen Madison branch and reloaded for the alternate branch if needed.
• Finished Amy’s Scavenger Hunt branch or saved before the bail/continue choice.
• Finished Stephanie and Brittney route branches separately.
• Made a separate Patrick/Rachael/Frank save for Compubrah, thermos, phone, and fight achievements.
• Handled Vickie invite and training only after prerequisites are stable.
• Completed Liz Katz, Doja Cat, and Nocturnal Temptations on dedicated DLC saves.
• Did bad-outcome achievements on throwaway saves.
• Exited and refreshed Steam if a completed achievement has not appeared outside the game.
