The game is about a mission of The Rebellion against military oppositions setting in the pacific ocean including (battleship, aircraft, and submarine) with various weapons that makes game fun. :)
Player as a marine must complete the mission to protect Offshore Refinery/Oil Rigs until the end. If you're fail with this task, The World War III can not be avoided, OMG :P
Upgrade your battleship becomes stronger and powerful because in every level the enemy's combat vehicles will never let you survive. They're going WILD.
Watch out with the Commander Battleship at the last stage - (Huge, Sophisticated, Armed, and Strong), I'm not sure you can Kick its Ass....
So get your mission, have fun... :)
