Obsolescence
This game gets so intense! It's just boss fight after boss fight after boss fight! Super easy mechanics that you can learn instantlly, just move left and right, avoid everything and try to have your laser hit the weak spot in the middle. Blast through rows and rows of moving armor. As you progress the bosses will start to try to take you out too, so watch out for their intense lasers, rockets, and bullets! You have to have awesome reflexes to get far in this one. Good luck!
