A pretty fun game IF you enjoy doing the same thing over and over and over..again..until..you finally get tired of it =P
The graphics is probably one of its best factors of the game. Overdrives and Time Extend looks cool and Menace are well, mostly average. There isn't much of a value of the game except for....OH! There's a menace! We'll have to KILL it!
Overall Crimson Sea 2 is an average Sci-Fi Shooter Game with cool moves and graphics but a really pointless storyline to it. After you play it for a while, you'll won't want to touch it for a really long time...(unless you really hate those little monsters)
One of the WORST things i think that KOEI should've thought about is the setting and the limit in places you can go to. Before the mission, you have the same procedure: Base, Select Mission, Go and Shoot. After the mission you also have same procedure: Go Back to Base...This is like the most major factor that made this game so BORING!!
