Shoot N Door is a shooter game where you kill enemies and loot weapons.

In this game, you have to go through positive and negative gates. These gates will determine the number of your army and the weapons you will use. There are also obstacle gates you will have to overcome along the way.

Your arithmetic skills can be a great help in which gates you should pass through, as they can either increase or decrease your number of allies. If you pass through the right ones, you will win against the enemies. If you choose the wrong ones, you will fail to complete the game.
