Standard can teach the wrong geometry. Teammates may stand in one another’s muzzle line, rockets can be fired through a crowded doorway, and the run still continues. At Intense and above, launch information and the current reference agree that player-to-player damage is active. Before raising difficulty, rebuild the squad around lanes, crossing rules, and an open recovery route.
For the August 25, 2026 build with Patch 1, check whether team damage is enabled at the selected difficulty, whether the player controls an attack’s placement, and whether the current tooltip or a safe pre-fight test confirms its behavior. Fixed friendly-fire percentages are unreliable because developer reporting describes per-ability tuning and the patch already changed explosive behavior.
Draw the retreat lane before assigning targets
Pick the direction the team will move when the hold breaks. That route belongs to movement, not damage-over-time fields, mines, a turret body, or a player who refuses to yield position. Only after the exit is clear should the squad divide the remaining approaches into firing lanes.
A four-player room usually needs three jobs rather than four independent crosshairs: the main approach, the side or ceiling route, and priority-target control. The fourth player floats between support and the side that is losing ground. If all four Marines shoot the same doorway, the first Warden, Drone, or Synth flank forces a turn through friendly bodies.
- Point lane: the clearest long sightline, held by stable rifle or precision fire.
- Pressure lane: the approach most likely to fill with basic enemies, reserved for controlled area damage.
- Control lane: the space around the squad where a grappler, Crusher, or Warden must be slowed or redirected.
- Retreat lane: no persistent hazard, no fixed deployable in the center, and no blind firing through it.
Crouching is useful because it creates a temporary vertical firing layer, but it is not permission to stack indefinitely. The front player crouches only while holding position and calls before standing. The rear player stops firing when the front player crosses or rolls. Patch 1 corrected several cover, mantle, crouch, and aim-side problems, so old clips of unusual movement should not define the current formation.
Use a crossing call instead of trusting peripheral vision
A player leaving a lane says “crossing” before moving. The shooter releases the trigger, confirms the body has cleared, then resumes. This matters most for flamethrowers, shotguns, explosive conversions, and heavy weapons whose dangerous area is wider than the reticle.
Keep callouts short enough to survive a swarm: “crossing left,” “rocket right,” “mine at door,” “Siren,” “fall back.” Explanations belong between encounters. If the squad is talking continuously, the warning that prevents a team hit competes with story dialogue and enemy cues.
When a random teammate ignores crossings, change your own weapon behavior. Swap to a controllable sidearm or narrow-fire primary while bodies are mixed, preserve the heavy tool for a clean line, and move laterally rather than shooting through the center. Damage not fired is cheaper than health that the Medic must restore.
Separate direct fire, splash, and unattended tools
| Tool shape | Main team risk | Safe release check | Abort signal |
|---|---|---|---|
| Rifle or rail shot | A teammate crosses the exact line | One visible target, clear space beyond it | Friendly silhouette enters the reticle |
| Shotgun or spread burst | The edge catches a moving ally | Front Marine is behind or beside the muzzle | The squad is rotating through the lane |
| Rocket, grenade, explosive round | Impact and splash are wider than aim | Call the landing area and keep an exit on the other side | Enemy reaches the human line |
| Flame or persistent zone | The attack occupies a path after firing | Place beyond the hold line, never on the retreat route | A revive or terminal interaction is inside the zone |
| Turret, drone, automated effect | It changes enemy movement and team spacing | Current client confirms team-damage behavior in a safe test | The device pulls the fight behind the formation |
Do not carry a remembered percentage from the first game into this one. The provided friendly-fire source reports that some automatic effects are exempt and flame or explosion team damage is reduced, but that is not a promise that every similarly named modifier behaves the same. Test the exact equipped variant against a consenting teammate before the encounter, or position it as if it can hurt until the current client proves otherwise.
Patch 1 changes what an explosive test should measure
The launch patch corrected small-explosion distance calculations, changed Duelist explosive conversions, clarified weak-point tradeoffs, and removed a damage and stopping-power penalty from High Explosive Rounds while retaining the conversion’s inherent weak-point cost. It also made Piercing Rounds unavailable to explosive weapons because that pairing had no useful effect.
Run two tests after changing an explosive loadout. First, fire into a clustered basic pack from a clean lane and observe whether the area effect actually removes pressure. Second, fire at an isolated armored or boss-sized target and compare time-to-stagger or weak-point performance. If the first improves but the second collapses, the modifier has a swarm job; it is not a universal upgrade.
Patch 1 also fixed an enemy-killed voice bark that could trigger on a friendly-fire kill. That detail confirms why audio alone is a poor success signal. Verify the target’s health bar and the teammate’s status instead of assuming a celebratory line means the intended enemy died.
Match elemental supplies to a weapon that can use the refill
At launch, Incendiary, Electroshock, and Cryogenic Rounds stack when the same supply is used again, and the matching supply can refill a weapon of that elemental type. That creates a resource decision: an elemental pack may be both damage preparation and ammunition recovery. Do not consume it automatically at the first crate.
Before pickup, name the enemy faction and the next hold. Fire, cryogenic, electric, and piercing tools have different jobs against Xenomorphs, Pathogen creatures, and Security Synths. Use the supply on the player whose weapon and assigned lane can convert it into a controlled advantage. The teammate with a mismatched weapon or a blocked lane gains less even if the tooltip looks attractive.
Reserve one predictable weapon for mixed-body moments. A sidearm with a narrow line and known recoil gives you a legal shot while the heavy weapon is unsafe and the room changes shape.
Enemy behavior decides when the formation may split
The official Xenomorph showcase gives each special a formation problem. Use that behavior to decide whether the squad should compress, fan out, or focus a single target.
| Threat | What breaks if ignored | Formation response |
|---|---|---|
| Siren | Calls additional enemies into an otherwise stable fight | Keep lanes, but transfer focused fire immediately |
| Drone | Uses vents and speed to ambush, then escapes weak pressure | Commit several weapons to the called target without chasing into side rooms |
| Warden | Controls space, accelerates suddenly, and knocks Marines down | Fan to multiple angles while preserving the retreat lane |
| Crusher | Frontal armor punishes head-on shooting | One player holds attention while clear side shots attack the flank |
| Exploder | Forces a panic dodge and can scatter the line | Back off, shoot it before contact, and use its blast against the pack |
| Praetorian | Fast melee and grapple pressure remove a Marine from the fight | Maintain range and cover; do not crowd the grapple victim’s lane |
| Harbinger | Long leap knocks a player down | Open distance and use long-range fire before the leap window |
| Striker | Relentless pursuit and sweeping attacks overpower a thin lane | Call heavy fire, then rotate together instead of four separate dodges |
A Facehugger is low on the official threat scale but demands floor awareness, especially around eggs. The nearest player calls it; the player with a clean downward angle removes it. Four Marines all aiming down creates the perfect moment for a larger threat to enter unseen.
Move up from Standard only after three clean readbacks
Use a familiar mission rather than new story content for the first Intense test. Clear it on Standard with three conditions: no player repeatedly fires through another, the retreat lane remains open during every hold, and the team reaches each resupply with at least one controlled weapon option. Then repeat on Intense without changing four builds at once.
- Pre-drop readback: every player names a lane, a crossing word, and the attack that requires a call.
- First hold readback: verify whether the front player can crouch and stand without entering rear fire.
- First special readback: one voice names the priority target; the others keep their assigned geometry.
- First down readback: stop area fire, clear the pickup zone, and let the designated support interact.
- Post-room readback: identify whether lost health came from enemies, teammates, or a blocked retreat before spending the next resource.
If the squad fails the same readback twice, lower difficulty or change one tool. A run is not ready for Extreme because its damage is high; it is ready when the group can explain where every Marine may move during a surge. The class and Specialist guide helps replace the tool that does not fit its lane, while the campaign checkpoint guide identifies repeatable rooms without inventing a fastest route.
