Galaxy Strike (also released as "Space Strike") is a scrolling space shooter. Using your mouse or keyboard, you must make your way through the enemy, killing them as you go. The enemy come at you in continuous waves through twenty progressively harder missions. You begin with an impulse gun. As you progress, you can pick up items to upgrade your impulse gun or even upgrade to a more powerful quantum laser or wave gun. You will also pick up secondary weapons like heat seeking missiles, the annihilator cannon or a nuclear bomb.
