- Nuclear Nightmare V5.0.2 - 8 December 2025
Patch Notes: - Gas canister explosion stack overflow crash fixed (This crash occurs when a gas canister blows up from another object blowing up, you may have experienced this crash even if a laser went off next to a gas canister item) - Level streaming values optimized/Crash fixes (Tweaked streaming values to be more optimized for lower-end pcs, i.e. before we tried to load areas very fast by dedicating a high amount of ms per frame at a close range to the POI, Now we load the area from a far distance with low ms per frame with the trade off of a longer load time. However this shouldn't be an issue as areas are loaded further) - Examine tasks now finish earlier (A lot of players were confused and thought they finished the task when they really didn't, so I made it finish slightly early to mitigate this) - Drones preparation task counted as classified fixed - Session error messages updat…

We plan on adding/remaking all of the skins that exi…
