Omega Five

Beat the entire arcade mode without dying using Ruby. Ruby's Type B (blue) weapon is a must. The fully powered laser can clear most enemies in record time and bounce off walls. Learn to use the anchor weapon on tougher enemies and bosses. Latch on and concentrate on dodging. Let the anchor do the damage and apply primary fire only when safe. Learn to use dimension shield, it takes far less health to use then getting shot will. You can also use the anchor to block enemy fire as well. Sometimes it will save you trouble of using dimension shield.

Note: Changing your character requires a continue. Do not change characters whatsoever.
