I can't find a good, working zombie mod out there for this game yet. Any clues, anyone? Only interested in single player :)
Mods that I can recall being used:
- Extreme Graphics Enhancement v2.85 (enhances various things about GTA IV)
- Visual IV (enhances graphics)
- More Liberty City V3 (more pedestrians and traffic)
- Arcade 2.0 (weapon sound pack)
No ENB, I hate ENB.
Oh, and if you don't have GTA IV, I recommend checking out this guy's blog!
