I bought the game last night. I enjoyed the previous incarnation so thought I'd give it a go. To be honest, not really that impressed. For a start I finished the game in one sitting, about 4 hours on normal. I know there is MP and co-op, but still. There were some good levels but others had the feel of being very compact and short and others were just a jumbled mess. Loads of weapons, but not really needed. Graphically very good, the sound(score) was excellent. But thats it, no fireworks or OMG moments. It was just a sequel to a pretty good game. I would honestly say the first one was better.
