its not doom 3 , look at the graphics and you would know. Its doom , either 1 or 2 which was like wad... 10 11 12 years back? lolz I played doom 1 and 2 when I was like 4
yeh looks like a doom but not doom 3. graphics are to poor. probably something like final doom (only doom game i have )
i havnt been following the game so im not sure if its been done and it would be way too easy if i didnt edit it messed up
