Just tried the first stage and the game feels like a mix of Gears of War and Vanquish. The cover system doesn't snap as quickly as Gears does but it's serviceable. The controls are almost identical to Gears and Uncharted. The main character, Dan, looks like Chris from RE5 from the over-the-shoulder view - almost the same uniform too.
You can buy ammo and upgrades for your weapons, as well as skills that boost your health and all that. You get money from killing enemies and completing certain objectives throughout the stages. One objective had you go on top of a roof so you can jump on top of a mech, you're then in a mini-game sort of thing where you balance yourself while you're trying to shoot off its mechanized dome. Controls are intuitive so the process isn't as bad as you think it is.
Anyway, it's a decent third person shooter from the Yakuza devs. I'll probably buy it later though.
Oh yeah, had no performance issues on PS3. I think the game looks decent too. Voice acting isn't that bad either.
