Limitations
Modding for this version of the game is limited to replacing existing files. Custom code (such as LUA code) cannot be executed, making most custom logic impossible. However, some mods have made attempts to work around this limitation by abusing certain default game logic - such as adding additional events to a monster's animation file. This could result in, for example, an enemy firing two projectiles instead of one.
