Day 4

Day 4 Area 1

Boss

This boss's attack is unique as he throws these boulder-like projectiles at you that bounce off the ground.  Keep your eye open for breaks in the onslaught as they're the only way to keep from getting hit.

Day 4 Area 2

Boss

This boss takes a couple of shots and then disappears.  He then reappears in another part of the screen.  Not too difficult, just keep your eye on him.

Day 4 Area 3

Brief

Fire your weapons at the white areas on the screen.  These are weapons bays that will open and close.  When they open, fire.
