Aces of the Galaxy is a third-person, futuristic space shooter where the player needs to take on the entire Skurgian armada with a single craft after stealing it from them. The game is very hectic as various waves of enemies are sent in at the same time. Movement is not completely free, following the direction of the camera, but the player is able to influence the direction by moving towards the side of the screen or by performing barrel rolls.
There are different ships to choose from, all equipped with a chaingun and torpedoes. The torpedoes need some time to recharge but by holding a button they can be linked to target multiple enemies. Power-ups increase firepower, repair the ship or unlock the mission select screen at the end of the level. The game consists of main nine missions, but by picking up the warp power-up during the game there are three different environments to choose from. Larger enemies are highlighted red, the player can build up a bar to trigger temporal shift that slows down time, and there is button to scan for invisible enemies that usually grant a large amount of points.
There are three difficulty levels and various achievements to unlock.
