NOVA Near Orbit Vanguard Alliance PSP Gameplay

I do think N.O.V.A. Near Orbit Vanguard Alliance is at the same level of Halo, Gears of War, Call of Duty, and so many other first person shooters. The only advantage here is that NOVA is for the PSP. I still have yet to get used to fighting monsters. Here they gathered up killed me, I will be more careful next time. Nice game guys :)
