A nice game where you can warp in monsters using a machine gun and shoot them out against the wall by holding the shoot button. This game is compatible for both symbian 320x240 and 240x320 phones. Just download and install. Game will start in landscape mode. If you want to play in portrait (240x320) mode then click the green dial key, then click key 2 and then click the green dial key again. Screen will rotate to portrait mode. Never mess with the green key again it will mess up the game controls. You can set up your own keys.
