This update introduces a new MainLevel event along with a number of backend improvements and balance adjustments. As always, these changes are part of our ongoing development as a small, part-time team - we appreciate your continued support and feedback as we iterate (:
✈️ New: Airdrop Events
Airdrops have been added to MainLevel as a new dynamic event.
Airdrops occur at random intervals (approximately every 30–90 minutes)
Two airdrops are deployed per event filled with loot
Drops are focused further north (away from coastal spawn areas)
A plane flyover audio cue will signal incoming drops
This system is still in its early stages and may be adjusted based on feedback.
⚙️ Optimizations & Stability
We’ve made several backend improvements aimed at smoothing gameplay, especially during heavier server load:
Improved stability in certain AI types
Reduced unnecessary background processing in some AI/spawner systems
Limited worst-case workload during heavy spawn calculations
Made POI scanning more incremental to help distribute server load more evenly
These changes are part of ongoing performance work and will continue to be refined.
🧪 In Development
Added an early Teleporter Blueprint
Not currently active in gameplay
Part of internal testing for future systems
Shares underlying logic with the existing ladder/mount system (shoutout Cweepa)
🛠️ Fixes
Fixed an issue where sewer audio cues could be heard above ground
⚖️ Balance Changes
Civilian AI Balance Changes:
Ammo reduced by ~50%
Bullet damage reduced from 15 -> 10
Reduced overall food spawn rates
Notes- We’re continuing to test and iterate on systems like airdrops and AI behavior. Some values and mechanics may change as we gather more feedback and performance data. If something feels off or you run into issues, please let us know- it genuinely helps us improve the game.
As always, thank you survivors!
