I'm surprised I looked past this one. It's one of the highest rated games I have not played before! It's not very hard to see why. It's really cool to see all this stuff going on at once. I like it how I seem to always be able to come back. Of course, that also meant it was easy for me to die.
It takes awhile to get the hang of. The graphics are quite good. The sounds are also really cool and it's a pretty clear cut game where you just have to shoot everything but your partner when it gets going. There's a lot going on with all the upgrades. A bit too complicated to skim past.
