Once again, you play as the space marine we lovingly call Doom Guy who enters yet another hellish space colony only to find it overrun by more monsters than ever. They've, somehow, survived the last few times to revive themselves again to repopulate the new space colony's halls and corridors. I have to admit, out of all the Doom games I've played over the course of my lifetime, this has to be my all-time favorite. It looks better than the older games and sports new character designs and animation, plays like the older games but now in 3D, and doesn't play like a survival horror game like Doom 3. It's a completely new game or, should I say, original game from the ground up. Sure, there's no looking up and down, no precise aiming, no swimming, crouching or jumping like Quake or Quake II but you can't deny it's one heck of a game that can measure up to any of the others on the Nintendo 64. I will admit, Doom 64 would have benefitted greatly if you could have did those things. Just imagine it. The weapon's sounds and enemy's grunts will instantly bring back memories of what made playing Doom so great. It gives you that creepy feeling of dread when entering an area, making you wonder what lurks around the corner or up behind you. I think the thing I loved most about this game is that, at times, it's brutally hard and that's the way I love my Doom experience.
