Lately there's been a TON of the old school 2.5D FPS games on the App Store. From Wolfenstein 3D which was one of the first FPS games on the platform, and of all time, Doom Classic, Rise of the Triad, and plenty more have been ported. But some of the best havn't. So which ones do you guys want? I would personally like to see: -Hexen -Blood -Star Wars: Dark Forces -System Shock -A custom WAD loader for Doom Classic
It's sort of like a sub-genre of the FPS. It's what FPS games were like before full 3D graphics were around, where the characters, items, and things in the environment you can interact with are in 2D, but the levels are in 3D and it's an FPS. The most well-known would be Doom Classic, as well as Wolfenstein 3D and others. I also want to add a couple to my list: -Alien Trilogy -Strife -Outlaws (again by LucasArts) -Last Rites (with online co-op it could be pretty close to Left 4 Dead. LR is a pretty unknown game, just youtube "Last Rites Gameplay" to see what it is)
What about the "Marathon" series? I always liked that one back in the day. Also, the computer in the game (named Durandal) was wicked cool with a twisted sense of humor. Great old school 2.5D action that was!
