You play a pencil-drawn Stick Soldier and kill off any and all other (re-spawning) soldiers in the area before they kill you. You have a limited number of lives, but there are random items that may help your survival rate (e.g. weapons, armor, etc.)
The game is straightforward platform action, where you can move your little Stick Soldier to jump and shoot (in all directions) around the current platform stage. There are no "stages" or "levels" to advance in. You can play any one map available in the main menu.
There is also a game editor where you can edit and create your own map designs.
