• Classic Levels DLC
- Fix for baricades on MirrorImage

- Adjustments to Mouse Sensitivity slider to broaden the range of sensitivity

- Fix for special characters in leaderboard display names
- Fixed a bug that prevented Bilebats from shooting through Boulderchutes
- Added an option to use the command "NoAlienFX" in user.cfg to de-activate keyboard light effects for the game. This also may fix some game launch issues for Alienware users.

- Fixed a bug that caused Shaman-revived units to not be affected by Physics traps.
- Bile bats can no longer shoot through Boulder Chutes
- Fixed a bug that allowed skull farming with a "retry" of levels.
- Sorceress' sceptre fizzling is now fully fixeed.
- Void wall potions and coins fade after 2 minutes. This prevents a crash that would occur when there were dozens of them present in a level.
