Update 1.2 - Operation: Big Patch
Survivor Mercs Patch Notes — June 8, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
Commanders, thanks a lot for your detailed reports from the frontlines!
We were very excited about the v1.0 launch and tried to release a stable and fun version of Survivor Mercs. Unfortunately, some issues slipped past our tests.
We are very sorry for the inconveniences these may have caused you!
It took us a while and quite some work to fix these bugs, but we hope this update will finally resolve any remaining critical bugs particularly with some missions, unlocks and mini-boss stages.
IMPORTANT NOTE
You may have to play another run after updating the game to trigger the unlocks for the adjusted missions and objectives.
Here's the full list of fixes, adjustments and improvements in update 1.2:
MISSIONS & UNLOCKS
Weapons Lab should now unlock correctly. We changed the requirements for its mission and the path leading up to it.
Fixed confusing Mission UI. Now it correctly distinguishes between objectives to "reveal the actual mission" and objectives to "unlock the respective item". Also changed various "parent missions" to improve clarity on pre-required missions to reveal the actual unlock conditions.
Improved texts for mission objectives to make them clearer.
Changed mission for Override Dongle to prevent potential lock-up in overall mission progression.
Fixed dialogue triggers for various missions. The "extro" dialogues for completing a mission should now trigger more reliably and more immediately after a mission was completed. This may cause some dialogues for active or just-completed missions to trigger twice or at weird locations after updating the game.
Changed/added unlock conditions for these items:
Priest (Merc)
Override Dongle (Gear)
Steroids (Gear)
Airstrike (Weapon)
Weapons Lab (Room)
Comm Rooms (Room)
Maps #4, 5 and 6
Mission Rewards should now display immediately when returning to the Bunker HQ menu in all cases, i.e. also when returning from a "room" sub-menu.
Extended the underlying system for missions and overall progression tracking to dismiss "trackers" from previous savegames that are now obsolete. This may potentially cause some missions to potentially reset their progress after this update.
Fixed an issue with the same "trackers" potentially initializing with skewed values from a savegame, leading to progress for mission objectives becoming negative or never reaching the target value by resetting starting values.
Mission for Comm Rooms displays its correct title.
Tweaked construction & upgrade costs for a few Rooms.
Streamlined research costs for new Traits to be (mostly) consistent for each "ring". Generally reduced the BD costs and slightly increased DNA costs.
BOSSES, MINI-BOSSES & ENEMIES
Extended the countdown for Mini-Boss Stages by 30 seconds.
Completely overhauled and re-balanced the mini-bosses' HP & armor values. Every stage should now offer you a realistic chance to defeat the mini-boss in time, although not every squad-build will guarantee automatic success.
Increased HP on Krak-N boss to align it with its intended challenge level.
Mammoth now spawns the correct "Cannonfodder" enemy variants.
Fixed UI layout for multiple mini-boss HP bars.
OilRig's death VFX correctly spawn at its current location instead of the top position in the arena.
Reduced Auto-Extraction timer after defeating a boss to 15 seconds.
Fixed potential mismatch of armor icons and armor decay indicators on enemy HP UI & HUD.
MERCS, GEAR, WEAPONS
Spark no longer shoots in the opposite direction of his targets.
Mercs don't stick too close to the Commander and should face their movement & aim directions more reliably.
Fixed time between DoT ticks for various Mercs.
Fixed modifiers for Shredder's shots-per-attack upgrade.
Pistol, SMG and Chem-Launcher show the correct texts for their special stats.
Fixed some "lingering" effects (acid puddles, scorch marks, etc.) not updating correctly with upgrade modifiers. Adjusted some upgrades to balance stacking modifiers for Linger Duration.
Fixed some attack VFX not correctly reflecting the "area of effect" modifiers.
Improved movement & attack behavior for Silverback.
Fixed some Gear upgrades displaying confusing stat modifiers.
Fixed critical hit chance modifiers sometimes not affecting Commander Weapons correctly.
ADDITIONAL FIXES & IMPROVEMENTS
Fixed a potential issue for Krak-N Achievement not unlocking on Steam.
Increased scroll speed for mousewheel and various auto-scroll UI panels.
Fixed the description for the "Dogtag Galore" award & achievement.
Fixed an error in the Armory that could break navigation.
Adjusted color scheme, size and layout for active mission UI in Bunker and Briefing Room.
"Retreat" popup is now different from "Abort Operation" to make it visually more clear when you're safely extracting with your squad alive and when you're killing off your squad.
Fixed duplicate modifiers showing for Elite Ops.
Fixed some permanent upgrades not showing in the Commander Stats in Clone Bay (before starting an Op).
Added icons for stats & modifiers affecting enemies in stat list UIs.
Fixed some colliders for environmental assets to prevent characters from getting stuck or behaving erratically around some obstacles.
Fixed Payload objective leaving behind an invisible collider.
Fixed an issue with environmental assets not spawning correctly.
Improved rendering performance for HUD.
Improved performance for spawning enemies.
Reduced the occurrence of micro-lags when spawning or de-spawning many objects.
Removed some misleading labels from some rooms.
Fixed some typos in EN, DE & ZH languages.
Mod menu shows more info about the mods and will list mods that are still loading.
ModdingTemplate includes a modding guide PDF to explain in detail how to create custom skins.
ModdingTemplate config includes the PreviewImage to upload a cover to Steam Workshop.
This update will also be available to the console versions of the game in the next few days.
