Outbreak: Infectious Zombie Mod for GTA 4 is a small scripted mod that will turn Liberty City into a city of zombies. Grab your shotgun and take an active part in shooting the evil spirits!
Works on patches 1.0.4.0 and 1.0.7.0, requires Scripthook.
The mod works in spirit modes. Zombies and Pedestrians: The infection spreads rapidly throughout the city, anyone can become infected - police, bodyguards and even you... There is a bite meter and before it reaches 100%, you need to find an ambulance and heal in it.
The other mode is just with zombies. They bite the same way, but the victim is now only you, there are no more innocents left.
You can play as Niko, as well as for the police (four partners) or special forces (eight partners). You can hire bodyguards (give them invulnerability).
Plus, you can include random events in the form of car explosions, randomly armed civilians and other trifles.
