Crimson Sea Hints for XBox
Fail the first mission 4 times to unlock g-squad mode and is very easy and bosses are weak,then restart your game on g-squad mode
To beat the final boss just keep moving and dodging and don't stop shooting.
Learn his attacks at first than keep dodging and never NEVER stop shooting until your overheated.
This is the easiest way I have found to beat this boss.
P.S. If your waiting for the second Crimson Sea don't it is only for Playstation Two.
