What, are they serious...?
For this is not a true game, but a mutant of a game, its the after-birth of a beautiful angel.
It could have been so much better but instead it was made poorly.
Firstly the PSP has let the genre down again. This console is not designed to play FPS (which is strange as FPS are now the mainstream in most households), I don't know why people keep trying to make FPS on this console because they just dont work.
The second problem is the poor gameplay, the enemies are boring, they have rubbish AI (which usually involves running away when getting shot at and then standing still again when they are not being shot at) and the dull scenery.
If you want a handheld FPS then get a DS (and no this is not one of those reviews where I just try and turn people against the PSP and go for the DS). Honestly, get Goldeneye (it is not very good but it plays well) or better still wait for Metroid prime Hunters because (going from the demo and footage) it is going to rock and the online will pwn.
The main reason not to get this game is because it destroys all that is good about the japanese anime film (often refered to as "the greatest anime ever").
On the whole if you want a decent game for the PSP then look much further than this, avoid this game like it had the plague, a dead mouse in the box and it was covered in human blood. AVOID. You have been warned.
