I spent some time this morning talking with Tom Mustaine of Escalation Studios and John Carmack of id Software regarding today's release of "DOOM Resurrection" on the iPhone. Unlike previous "DOOM" games, "Resurrection" takes control of the player's movements, leading you about the environment almost like an arcade light-gun game. Originally this style of gameplay was implimented simply because id wasn't sure if they could pull off a standard FPS on the iPhone. Carmack explains:
"At the beginning [of development] it wasn't clear that traditional first person shooter controls worked. None of the demo games that people had made were any good at all from an FPS standpoint. So we thought we'd look at the platform from scratch and say 'What type of gameplay would work here?' regardless of what we had done in the past."
