SCEE sent me Ghosthunter (and Ratchet & Clank - Keep this in mind when reading my sig)...
I played Ghosthunter for a bit last night. It seems OK, but I haven't played for long.
I'll give a brief overview but will try to keep it spoiler free!
Basically, it's Ghostbusters except not as cool.
You're this police guy, who's send to this abandoned school cos builders hear dodgy noises, etc...
So you go there with your partner, have to look around, something happens, blah...
You run around a bit like Resident Evil, except you can press circle to switch to a behind the shoulder-ish view, where a cursor appears onscreen which shows where you're aiming, R1 fires. From there you can press circle again to go back to normal movement or triangle to switch to first-person, to allow for more precise aiming. Movement through doors, up ladders, etc... is done like Resident Evil.
You get a weapon which is used to get the ghosts... you have you shoot at them, and then when they're... something, you press R2 to throw this grenade thing at them, that catches the Ghost and then flies back into your hand, and you carry on. Very Ghostbusters inspired!
It seems like fun. The most impressive thing about it so far is both the controls, which are layed out very nicely (although the camera work takes some getting used to) and the lighting. Your weapon has a torch and I didn't realise the PS2 could do lighting effects this well. Looks damn good!
