You start off as a pilot in space, still training in a test flight with the Prostar spacecraft, when suddenly attack drones show up and you're forced to investigate just whatever it is that's going on. Apparently the Prostar is some sort of experimental spacecraft and it just isn't very powerful in any way at first, so you'll have to upgrade its armor, shields, engines, blasters, launcher and missiles yourself at the cost of crystals you'll find along the way. Controls- To move around, you can use either the arrow keys or W, A, S and D instead. To use your main attack blaster, use C or I and to use missiles, use X or O. You can also use a special attack with Z or P. Protostar is one of our many Arcade Games that we publish on TheGamerStop.com. This game is also tagged as a Space Shooting game.
