Saintrooper is a challenging exploration platform game that takes place mostly under water, where your character has to swim up for air often or collect oxygen tanks to prevent from losing valuable hearts. The game ends if you run out of lives, but players can always continue playing from the last level attempted by using the stage select option shown after the control selection menu.

One key feature of the game is that you have the ability to grab on to walls and climb upwards by jumping off a vertical surface. You can shoot in four different directions, and acquiring the special power-up item will temporary increase your firepower and oxygen reserves. By firing downwards during a freefall, it is even possible to reduce the falling speed and soften the impact of your landing.

There is an exit to be found somewhere in each level, but to get there you would first have to find a set of keys and unlock the doors that prevent you from reaching them easily. Leaving treasures uncollected might not be a good idea either, since extra lives are given out generously whenever you've scored a certain amount of points during your rescue mission.
