This mod adds Blain (Jesse Ventura) from Predator into the game as a Marine skin (face only at the present time). This mod also includes three taunts from the film - a fourth was not added due to the poor amount of good quality sound samples available.
The Hive Infiltration Unit was an early idea of the USCM - to camouflage themselves in Xenomorph-styled armor to avoid detection. Unfortunately, they failed because they didn't realise that the Aliens tracked by pheromones.
