"GNPC: So was the expansion back motivated by continuing the story, or was it about content that you couldn't fit into the original game…?

Matt Hooper: There wasn't a whole lot of a conscious effort to say, 'Hey, we can't fit this in DooM 3, let's move it over to the expansion. There probably are a couple of things just by default that worked their way into the expansion because we thought it worked better. Like some of the weapons, for instance. DooM 3 has such a huge arsenal of weapons. It's like, everything ever created. There's, you know, a couple different machine guns, and there's plasma guns, there's projectile weapons, there's rocket launchers--there's just everything. There was no room to fit other things.

So when we started talking about the expansion, that's why we added things like the grabber weapon that throws back the enemies' projectiles, because we thought that was new and fresh, and we didn't want to just introduce some new machine gun, or something like that. There was a lot of clamoring for the double-barreled shotgun in DooM 3, so we had to add that back in there. But there wasn't this holding back of things that we didn't want to do in DooM 3. It was more just, 'Hey, let's do what's cool for the expansion.'"

"Another new addition to the Resurrection of Evil arsenal is the strange alien artifact you find at the very beginning of the game. The "new" Doctor Betruger (now with 750% more evil!) sends three major "hunter" demons after you to retrieve the artifact, who you face individually at key moments. Each time you defeat a hunter, the artifact gains a new ability. The first confrontation happens pretty early in the game, and once you beat the boss, the artifact gains the ability to launch you into "Hell Time," where everything but you slows down."

"Even with 'thinner slices,' the game still looks and plays just like the PC original. The entire story is here with nothing ending up on the cutting room floor. In some aspects, playing the game on a console promises to deliver an even better experience thanks to the easy hook-up to a home theater system. A big screen TV and surround-sound system are the perfect equipment for this type of chilling action game."

"The Xbox though is a system that stays the same, which made it a little more challenging to get everything we wanted to get in. We still took the time though to make sure that we had the cooperative campaign in, which is the first time that you can play Doom 3 in a co-op mode. All the other modes like deathmatch and team deathmatch are all included in the Xbox version that can be played either through system link or Xbox live."

"Although the single player game is more or less the same as the PC version, there has been one major addition to the multiplayer side of things. Players now have the option of teaming up and battling Hell's minions via Xbox Live or system link, a feature that's extremely entertaining for a number of reasons. Unlike many games, you don't need to play through the single player portion of the title if you want to play cooperatively, you can simply hop on Live, find a partner, and choose the level that you want to play. While most of the single player levels made it into the co-op mode, nearly all of them have been reworked to make the experience more enjoyable for multiple players. The layout is a bit different, and monsters spawn in different areas, so it's almost like you're playing a new and original game."
