... Doom guys come to stand
STRONG! Rrip n Tear! 
This is merely just a concept art still. most of the inventory items are just photoshopped in, exept the inventory doll (still in messy state) and the shotguns. Battlescape doomguys are real deal, only needs editing in arms at leg parts still. after that its quite easy to change palette to megaarmor (blueis armor) by just changing the palette.
Thinking of it, it would be fun to replace Xcom tech with doom tech. meaning that there would be no xcom weapons or fancy things. You would start the game only with the first weapons that doom had.. with doom pistol and Knuckles (knuckles would work as melee and stun) .. then just researching forward for example:
Chainsaw -> Shotgun -> shotgun ammo -> Super Shotgun -> Minigun -> Minigunammo -> Rocketlauncher -> rocketlauncher etc etc...
Side reserches would be Stimpack -> Medikit -> Armor II -> Armorr III etc etc.. something like that.
Or even dem Powerups research ... Berserk, Partial invisibility, megasphere .. well these would prolly be impossible to code i guess.
But yup.. concepts :3
