Astro Avenger 2 - World 1 Levels 1-5
These are the first five levels in the game.They are very easy,and you should be able to beat them without dying.This is my strategy for these levels:upgrade the driller to level 4,sell all your rockets,and do not repair your ship.You can easily get a repair bonus if your health drops down to 15%.Also,the music in these levels is great!
