RE5 isn't bad, gets better if you play co-op. the partner AI is stupid on hard and almost nonexistent on professional. 5 also builds off the Las Plagas parasites from 4, but the parasites have been combined with the Progenerator virus, the precursor to the T virus. The gameplay isn't bad in 5, but i preferred the feel of 4. At least Chris has a real knife compared to Leon's and a decent beginning handgun. Also, every gun you get can be made infinite after beating the game. Infinite magnums are so much fun.
