Inventory, battlescape or all?
I wouldn't mind helping out here and there, and can do a bit of spriting sometimes. It'll be pretty rare and random though.
I'll be back in a jiffy (ie, 2-3 days).
ps. you are totally wrong about the Assault Cannon w/Expl. Balls not being OP. There's better artillery, but none cheaper or more accessible that early. Half of it is the game engine's fault though (concussive, within 3-squares hitting under armour, the usefulness of arcing weapons, etc). If only the game wasn't based around live captures.....
Everything counts in large numbers, and 4-6 cannons are easy to get and make the ammo for. Then again, prods are almost free in comparison, and are amazing for where they are on the tech tree.
Anyway, I'll chuck something together in psp7 for battlescape paper-doll and inventory. Do you still want the "army" look, or tech it up a bit?
