Killer Mario is an exciting game with your hero, a game where you need the w, a, s, d, keys to move with Mario and the mouse to attack the opponents or to shoot them. At the beginning you have just a weapon that you can use to hit the opponents but on the track you will find also guns and then you can shoot the enemies. You have to move forward towards the right side of the screen until you reach the destination. There will be a lot of enemies on the way and you have to kill them if you want to survive, if you want to complete your mission in every level. In this game you have to use 1, 2, 3, 4 to change the weapons. If you ran out of ammo with a gun you can change it with another one which has ammo. In this game is important to collect bonuses from the road if you want a big score. If you kill enemies you will get extra points. Don`t hurry to judge the game`s difficulty even though the first level is simple because you have to be more careful as you progress in higher levels where things are getting pretty difficult.
