+1 FPS has been on HiTech's to-do-list for years. His original idea was to allow FPS players to capture a command bunker complex, thereby capturing the base. Defenders would of course be able to spawn in defense. I haven't directly spoken to Dale in a number of years now, so I don't know where (or if) this still falls on his AH bucket list. Anything that adds a new dimension to the game (and, therefore, expands the player base) is a good thing, in general.
