Metal Arms: Gitch in the System
One of the most 6th gen games I've ever played. Very derivative. It's taking primarily from Halo, with medium to large sized areas and vehicles that shoot laser beams and fragile infantry that throw their arms in the air and run away screaming if you hit them a few times. It's also probably taking a bit from Ratchet and Clank, with its third person camera, cart-wheeling double jump, and irreverent, cartoony presentation, but there's only a year separating these games, so perhaps not.
In execution, it's pretty shaky. character movement can be cumbersome and shooting feels weightless. While enemies can have their limbs/weapons damaged and blown off, there's little strategic value in doing it, and even if you wanted to, none of the guns feel accurate enough to do so. Enemies are bullet sponges, and it's just a better idea to shoot center-mass with whatever powerful weapon you have ammo for.
There's some variety (driving sequences, espionage, etc.), but it only seems to be there to elongate the experience, and the game doesn't feel very confident straying from arena and vehicle combat. If it played better and was more concise, it could be a cult classic worth embracing.
