Are those Avikan-made guns? They have their desert tan and steel black color scheme. Though, don't recall if they have SMGs...

No, I made these myself. They're supposed to be TDI vectors. (the sprites I mean, the code for the guns is from RPG growth, I just made a different sprite for them because the RPG growth guns have somewhat lackluster sprites)
