First things first. I loved this game - fresh, inventive and with a bit of humour. Had this come out 5 years ago it might have been the biggest thing since Half-Life, and would have (passed water) all over the mediocrity that was Doom 3.
These mothers are fast. Wait, make that FAST. It's the game version of DoTD, and you thank your stars they didn't move like this in Dead Rising. The weapons feel suitably hefty, with a satisfying amount of gore on the good head- and limb-shots, whilst the reload times are pitched *exactly* right for maximum tension.
So far so good! And worthy of the BAFTA award.
But.... for my sins, I'm a 360 offliner and therefore not getting the most from this game. The AI of your associates, whilst not Resi-Evil bad, is still pretty lame - I've lost count of the number of times one or more of them has wandered backwards into a clutch of the zombies. Maybe my mates would be that stupid, but I doubt it (hopefully!) The bosses are also repetitive and unchallenging after a while - even the Tank is easily dealt with, given the right weapon selection.
The graphics are not spectacular but they are bright and clear (and fast! which is the priority), and it is usually possible to see what is going on around you - the use of lighting is especially good in the indoor bits. The sound is OK, however the main drawback seems to be the replayability especially for the solo player - whilst the game works, and works OK, the addition of more plot elements to each level and the usage of more items and explosives etc, would have added a great deal more to the game. Vehicles in the sequel perhaps?....
As an offliner this is a solid and fun 3.5/5 - as an onliner I'd imagine this is an absolute riot! :-)
