It didn't feel like you were swinging your heavy gun around to bring down the monster before he chews off your head,' said Carmack. Mustaine added, '[The shooting mechanic] was definitely a trial-and-error thing. You said the word "distilled," and that's definitely a word we've been using. We really wanted to distill the visceral Doom experience into the iPhone.' He also said, '... we have P2P co-op play that's not in the shipping version, but will come later. We didn't expect the 3.0 OS out so quickly! Two players join together, they see each other's cursors, and they either compete or co-op for a score. We're hoping to patch it in down the road. We're also looking at additional levels and potentially some stat-tracking stuff as well.'"
