Doom 3 (PC) Gameplay | 4k

It's been a while since I put some Doom 3 footage up. This is running off the Retail CD version of the game I bought in 2006. I tried booting the Steam version up, it's asking me for a CD Key for no reason, so I am playing the retail version in this footage. I will always defend Doom 3. I love this game.
