OK - so my friend was over earlir so we played the demo 2 players....
We had a fukkin blast so I bought the game and we played thru many of the stages...
I think the game is the best 2 stick shooter yet - the stages are soo varied, and the tasks are increasingly difficult and complex....its not a mindless shooter...some stages are battle stages, some are travel stages, some are puzzle stages, and theres just so much variety in the full game. (lets see how many stages total - that I dont know but it looks like ALOT from how far iv gotten.)
The music is very good - its electronica with bleep beats.
The stage titles and theemes are intriguing....
At one point me and my friend had to transport cells from one organism to another in a blood stream flooded with bacteria swooping and piercing down on us.we would take turns where one player would transport and the other player would snipe...it was very fun...
You can move with the left stick - shoot with the right...L1 is "squirt" or dash L2 is plasma burst. R2 is tractor beam
you can absorb plasma and then fire devastating plasma bursts or plasma can collect in certain spots and form powerups that enhance you weapon.
You can use the tractor beam to drag cells around and use them as cover, or to move cells into or from organisms as needed.
The demo is free - I highly recommend trying co-op on the demo. Thats what sold me on this game.
