Space Sentinel is a spaceship simulator, where you protect the homeworld from invading enemy fleet and incoming meteors. Your spacecraft is our last remaining starfighter, although already damaged, it is still a pretty powerful and it is equipped with a scanners, dual lasers, targeting system, hyperdrive and shielding for the ship's defence. The enemyfleet is using different types of spaceships in their invasion task force: swift, stealthy and unshielded small fighters, shielded/cloaked cruisers, bulky cargoships and several large space stations. The two smaller classes of enemyships fly around in packs of two or three while the larger enemy warships are waiting on the edge of the system. The mission is to destroy all enemies and remaining asteroids located in starmap before fuel/energy runs out.
