The MTX-343 Assault Mech was used from 2251 to 2300 by various military organizations. It was commonly referred to as a "Raindrop" by its crew because of its 32 rapid-fire missile launchers. It was also equipped with a highly accurate and effective coilgun, and two standard 40 mm cannons.
If you're not familiar with a coilgun, check out the Gauss cannons and the MACs in Halo.
I also added a little "transforming" feature, which allows it to turn into a gunship of sorts.
Soooo, why do I have this picture in here? Well, I need some help. I've made this fairly large diorama that's too big for my "photo-taking area" (this was the only pic I could take without the rest of my room showing). I really can't afford photoshop, so I want YOUR advice on how to take a random background and edit in a solid color (white, black, etc.). Thanks!
