关于此试用版

Alien forces have invaded our galaxy, crushing Earth's defenses in a brutal campaign to seize control of the entire universe. Your ship is equipped with multiple lasers and an auto-turret that can utilize power ups for temporary upgrades as you mercilessly dodge bullets and try to survive the enemy onslaught. Defeat the invading aliens and save our universe!

As a new recruit in Alpha Force the demo version will give you access to the first four missions of your enlistment and 7 different equipment items that you can unlock for your ship. 

The demo includes several unique enemy types that have their own behaviors and weaknesses. Make sure your ship is equipped for the mission ahead!
