This firetruck is for Zombie Panic! Source. The ambulance needed a big brother. Also, it was just a crying shame having such a successful zombie mod that didn't have any proper emergency vehicles. The players and other developers couldn't be happier to add it to our repository of original models. We've been trying to get away from ported assets and Half Life 2 content for quite some time. And I'm happy to fill the void of competent modelers that the team has been lacking for years. While this asset is compiled specifically for Source Engine, I wouldn't mind at all making it available for use in any game on any engine.
