Yeti3D is a game similar to Doom. Yeti3D is a full 3D first-person shooter game. The main point of the game is to kill all the enemies with your gun that shoots white orbs. There is only one level, so once you kill everything that is it. You have a limited amount of ammo and health. If you lose all of your health it is “game over”. There are cubes that give you more ammo and more health. Yeti3D can run in portrait or landscape mode, and it has a number of different control schemes. Though, I cannot recommend this game. There are many problems with it, like you run out ammo to quickly, only one level, and the controls feel very clunky. But, if you want to try it out you can get Yeti3D from the MarcoGiorgini.com source. There are some screen shots below .
