Acheron is an upcoming modification for Battlefield 2142. It aims to offer the players the ultimate Colonial Marines experience (within the limits of the Refractor engine).
Based on the BF2 US and BF2142 EU soldier models and heavily modified to resemble the USCM concept.
The heavy soldier's shin armour is that of the 2142 EU heavy soldier and should be modified before any texturing.
For practical reasons, the iconic USCM body armour will be part of the kit meshes available to both light and heavy soldier.
Well if the marines can't kill the xenomorph's with guns, might as well choke them to death by getting some of the armor stuck in their throats when being their chow.
