- Bug: Game Crashes Under Specific Conditions and Workaround - 9 February 2025
Thank you all for playing UNDERWARD. We have received feedback through reviews and inquiries about the game "force closing" during play, and we would like to provide an explanation and workaround for this issue. Workaround This game was developed using UE5 and requires higher system specifications. Additionally, during multiplayer, the host (room creator) has a heavier load due to the amount of synchronization required. Check your PC's specs, and if they do not meet the "recommended specs" listed on the store, set the graphics quality to Low in OPTIONS. If you are using a high-resolution monitor such as a 4K monitor, you can reduce the load significantly by selecting Full Screen or Windowed mode and lowering the resolution. Do not select unlimited FPS (the lower the FPS, the less the load). (If playing with friends) Ask someone with a high-spec PC to host the game. Close any other CPU-…
