Hummer H1 Alpha
This vehicle was one of the cut cars of the released version of the game.
Vehicle was ported from a PS3 beta build, keeping all its original data (the files were updated to work on a PC version).
The vehicle is not accessible by the easydrive menu or jack spot. You need to spawn the car using a vehicle spawner.
Put the files that are inside the .rar file into the VEHICLES folder at the game installation directory.
