Use of this patch violates the [KF2 EULA](https://store.steampowered.com/eula/232090_eula_0) provisions that prohibit disassembling or modifying game files.
If this is a problem for you, use [SafeMutLoader](https://github.com/GenZmeY/KF2-SafeMutLoader/), which is completely legal.
- Game updates and integrity checks replace the executable file (`KFGameSteamServer.bin.x86_64`) with original one, so after these events the patch must be applied again
