That character I wanted to make a while back is still sat on hold, but I did spend some time on the weapon, and made it work in the good ol' BF2 engine.
Here is a little description I made up for it:
The Z1A3 Colonial Marine Corps martian issue battle rifle.
Its main armament is its .50 caliber riffeled barrel, with a 20 round mag.
This is intended for accurate medium and long range engagements over the wast martian plains. To support this a scope is standard issue for the marines stationed on mars.
For close quarter engagement it has a 5 round semi automatic shotgun in the handguard.
The weapon is made from light weight polymers, carbons and titanium alloys.


Still much animation tweaking work to do, not to mention the texturing of the weapon itself (I only layed out some of the base colors so far)
I updated the model to make it work with having two weapons (this updated and refined version still have to be imported)

Had a few funny moments messing around with bf2
