Insane extraction fails when the squad treats a temporary opening as another hold position. The bomb route opens, everyone keeps shooting, the progress-based horde thickens at the next gate, and the team begins its push after the useful seconds and deployables are already gone.
This strategy is bounded to Codename CURE II version 1.0.0.4 on August 2, 2026. It assumes the squad already understands Basic Training and Bomb Extract. The problem here is not learning five classes; it is turning five players into one moving formation under the current escape rules.
Assign the push, rear, and revive calls
Choose three voices before deployment. The push caller decides when the front has enough space to move. The rear caller says when a trailing wave, soldier, or Zog is about to catch the group. The revive caller decides whether a downed player can be recovered without turning one casualty into three.
Those are decisions, not permanent class locks. Pointman or Assault may lead through a dense lane; Support, Technician, or Sniper may watch the rear depending on the seed and available guns. What matters is that only one person changes the movement state. Five simultaneous opinions create five different distances from the objective.
Use the quick-chat wheel added in 1.0.0.4 when voice chat is unavailable. Hold Up marks a setup, Go commits the push, Supplies names a resupply stop, and Help requests a revive decision. The two-second chat cooldown makes a small agreed vocabulary more useful than repeated wheel spam.
Build the escape inventory before the bomb
The approach phase is not separate from extraction. It is where the squad decides which tools will still exist when the procedural route turns backward. Spend normal ammunition on loose infected, use melee on safe breakable glass when the current tile allows it, and reserve explosives for a blocked transition, alarm wave, forced Disciple, or final lane.
Support and Technician should deploy for a known trigger, not for every quiet corridor. Recover healthy equipment before leaving. If either tool is destroyed, version 1.0.0.1 says it will be regained on reaching the bomb site; verify that return on the HUD instead of assuming the ability is still unavailable.
Do not let scavenging stretch the formation across two tiles. Take visible metal and supplies when the rear is secure, but stop searching when the push caller reaches the next interaction. An attachment purchase after a failed mission cannot repay a wipe caused by one player checking a side room during a live alarm.
Keep an optional Disciple asleep
On Insane, the safest Disciple fight is the one the objective does not require. The boss-type enemy becomes dangerous after it is triggered, and Steam’s Do Not Disturb achievement confirms that a mission can end without waking one.
When fleshy ground announces the area, stop unsuppressed fire, grenades, and close movement until the route is identified. If a normal passage bypasses the Disciple, cross it as a group and restore normal noise only beyond the encounter. Do not use a risky movement exploit to save a few seconds; a procedural route can place the landing where the rest of the team cannot support it.
If a flesh gate makes the kill mandatory, finish the current ordinary wave first. Split firing angles far enough that one lunge does not hit the whole team, but keep both groups within revive distance. Version 1.0.0.2 increased afterburn damage to the Disciple, so a planned incendiary attack is supported. Combine it with focused fire, then recover deployables and regroup before touching the newly opened route.
Stage every trigger from the exit side
An alarm door, the last collected battery, the last destroyed spore, and the bomb are different interactions with the same tactical question: where will the squad move after activation?
- Clear the rear until the rear caller can name it as stable.
- Reload before interacting; current mechanics reports note that switches and pickups can interrupt reloads.
- Put the supply table behind the firing line and the turret on a side that watches an approach rather than shooting through teammates.
- Face the next door or route opening before the final interaction.
- Use the first area tool to create movement space, then recover it as the front crosses.
If a siren gate opens onto a packed group, one planned explosive at the opening is useful. Three players throwing at the same doorway wastes the answer needed for the next tile. The push caller should name who owns the first throw before the button is pressed.
Plant only after naming the first two moves
At the bomb site, point to the first opening and the first regroup location. The first move gets the squad out of the plant area. The second prevents the lead pair from continuing through a fork while Support and Technician are still recovering their equipment.
Version 1.0.0.3 slightly increased bomb timers across all regions, but the value is deliberately not treated as a universal script here. Procedural geometry changes the useful setup time, and future patches can change the number again. Finish the setup that controls the first gate; do not spend the whole timer trying to make the site perfectly clean.
Use the waiting period to top up, reload, and turn every player toward their assigned lane. A player looking for one last pickup when the route opens is already one decision behind.
Advance when geometry opens, not when firing stops
The 1.0.0.3 update moved the endless escape pressure away from a fixed countdown trigger. The bombard now responds primarily to how far players have progressed toward extraction. That makes old clock-based speedrun calls unreliable and gives the squad a better rule: move when the required door, bridge, or passage creates a traversable lane.
Clear the bodies that occupy that lane, throw area denial behind or beside it, and cross. Do not wait to kill every infected visible through the doorway. On Insane, a quiet screen is often produced by a stalled formation, not by a finished wave.
The rear player fires while walking and stops only for a threat that can physically catch the group. The middle players keep the lane open around downed infected and props. The lead player slows at blind corners long enough to choose the next route, then calls Go again. This is controlled movement, not a solo sprint.
Choose the live route with four checks
A procedural seed can invalidate a favorite left-or-right rule. At every real fork, the first player should make a short visual audit:
- Distance: which branch visibly reaches the marker or next opening sooner?
- Special pressure: which branch has fewer soldiers, Zogs, or a triggered Disciple?
- Width: which branch compresses common infected without trapping the squad behind one body?
- Continuity: which branch has fewer blind forks where the formation will split?
Make the call from current geometry, not from a guide screenshot. A longer branch with a clean, narrow lane can be better than a short open yard full of leaping dogs. Once the leader commits, everyone follows the same branch unless the route is physically blocked.
Adapt the push to Rust Belt Industrial
Rust Belt Industrial still uses procedural tiles, so there is no honest room-by-room Insane route. Its useful repeatable checks concern materials and lanes. Current mechanics testing reports that bullets can pass through open grating while solid metal sections block them. Confirm the surface with a safe shot before committing the whole magazine.
Break ordinary glass with melee when no live threat controls the other side, preserving ammunition and avoiding unnecessary noise near an optional Disciple. On narrow industrial corridors, put the turret far enough back that a player can retreat around it; use the Support table as cover only when it does not turn the sole path into a collision trap.
The Industrial achievement requires completing Rust Belt Industrial on Average or higher. It does not prove an Insane clear. For Insane practice, record which transition caused the failure – alarm door, required Disciple, first escape gate, or final corridor – and rebuild that transition on the next seed instead of memorizing one layout.
Give Zogs one defender, not five
Version 1.0.0.4 made Zog bite and leap audio clearer and adjusted the leap so it is accurate mainly at close range. The rear caller should identify the sound and assign the nearest free shooter. A player with the animal’s attention leaves a small lateral escape lane and avoids backing into the squad.
Fallen soldiers are slower but can hold the space the push needs. Focus one when it occupies the doorway; otherwise, move past threats that cannot catch the formation. The distinction is functional: kill what blocks, sidestep what misses, and do not rotate every gun away from the escape lane for one flanker.
Make the revive decision before reaching the zone
Version 1.0.0.3 reduces the escape timer to 20 seconds when all standing players are inside the zone. A downed player outside no longer forces every standing player to wait through the previous full condition. That change creates a decision point; it does not make every casualty expendable.
Attempt the revive when two players can reach the body, create space, and still return by the live route. One player covers the approach and one performs the revive while firing within the interaction’s limits. Abort if the recovery opens a second route between the rescuers and extraction.
Commit to the zone when the body is beyond a blocked gate, the rescue would split the final standing group, or the shortened timer is already the only repeatable finish. Say the decision clearly. The worst result is half the squad holding extraction while the other half begins an unsupported rescue.
Read each wipe as a transition error
| Failure | Likely transition error | Next-run repair |
|---|---|---|
| Overrun at an alarm gate | The final interaction happened before rear clear, reload, and deployables | Name the trigger owner and require a ready call from Support or Technician |
| Forced Disciple wipes the team | The boss was combined with an ordinary wave or players stacked one angle | Clear first, split supported angles, then apply the planned incendiary tool |
| Team stalls after the bomb | The group waited for silence instead of crossing the opening | Give one person the Go call and reserve one explosive for the first blockage |
| Lead reaches a fork alone | The second regroup point was never named | Plant only after assigning both the first move and the first regroup |
| Final rescue becomes a wipe | No revive authority existed and the standing group split | Use the two-player recovery test before anyone leaves the zone route |
An Insane clear is repeatable when the squad can explain why it moved, held, fought, skipped, or abandoned a recovery at each transition. The procedural seed changes the rooms; version 1.0.0.4 still rewards the same discipline.
Patch boundary and evidence limits
Release identity, co-op scope, classes, procedural regions, infected roster, CURE HQ, and official screenshots were verified on the official Codename CURE II Steam page. Raptor Byte’s 1.0.0.1 through 1.0.0.4 announcements establish the current equipment, Bomb Extract, Zog, quick-chat, and weapon-change boundary. Insane formation, trigger staging, Disciple decisions, and industrial checks were cross-checked among current community guides. Exact old escape clocks, uncertain drop counts, geometry exploits, and fixed procedural routes were not used.
