Fatal Freight is a 5-map campaign developed by myself (Tamari) with some help from friends here and there. The campaign supports all stock L4D2 gametypes (Versus, Survival, Scavenge, Coop).
These are a few samples of some of the custom 'germ' (horde) cues that will be featured in this campaign. As of right now, having a little trouble fully implementing them, but they sound great when they are working properly :)
