I made a few improvements for Campaign Mode Remake:
-Added a health bar for boss fights
-Fixed crashes in 2 maps
-Improved some boss fights
-Fixed a bug with Shrek boss fight where he didn't use range attack
-Reduced the size of the mod (by removing unnecessary files)
-Some minor fixes/improvements in levels
-Added subtitles
I'm also working on CO-OP mode for Garry's Mod.
I will release version 1.5 when I finish it.
