I really like FPS games, and having them in my pocket is awesome. I've found some good fps's, and some bad ones. Here is a list of the ones I own:
Modern Combat Sandstorm
This game is okay. The graphics are nice for an itouch game, and the detail put into the weapons and ironsight is amazing compared to some other games. The multiplayer is good, if you can actually get into a server. The only bad thing about multiplayer is shotgun campers :(
Price= $4.99
Wolfenstein 3d Platinum
This game is great. It was great fun on the computer, and has kept its epicness on its journey to the ipod touch. The game has some puzzle elements, like finding keys to open certain doors, and straight out combat. Shooting national socialists is quite entertaining. The controls aren't confusing. One stick to move around and tap a button to shoot.
This game has a lot of old school blood and gore, and this can't be turned off.
Price= $1.99
Eliminate PRO
This game is plain addicting. You fight against other players in different arenas. When you kill an enemy, a health pack and credits (Money) fly from their body. Be sure to get the credits, because you can use them to buy new guns and armor. There's one catch. You have a certain amount of energy, and each match drains your energy. If you have no energy, you can still play, but you won't get any credits. You need to wait 120 minutes for your energy to recharge, or you can buy energy for real money. Add me: kodak97

NOVA
This game wasn't the best game I have played. It surely was inspired by Halo, and you see that the moment you pick up the game. The campaign is a bit hard at first, and there is a lack of ammo in the levels. The multiplayer is the best part, except for the hackers, who have near infinite ammo and extremely fast reload times. If you find a server without hackers, it's an all out deathmatch.
Price= $6.99
Duke Nukem 3d
This game is fun, old school like wolfenstein. This game is one of the best fps's out there, except for the fact that the default controls SUCK. You can change them, and I reccomend doing so.
Price= $0.99
Call of Duty: World at war Zombies
This game is the most EPIC ipod touch fps ever. In case you don't know what the game is about, here's what happens. You are in some kind of building either by yourself or with other players via multiplayer. The windows are boarded up, and there are outlines of guns on the wall. Zombies come up to the windows and start to rip off the boards. You can kill them, repair the boards, or both. You can buy new guns from the outlines on the wall, and unlock new rooms by buying access. There are two maps, Nacht Der Untoten, and Verruckt. The graphics are amazing, and the bonus map Verruckt is worth the $5.00 you pay for it. I highly reccomend this game.
Price= $10.00
These are all of the Fps games I have so far. Post if you like any of these games, and if you found a good fps, post it, too.
