It's easy to forget (the RE series) also has its fair share of low points: lightgun shooter Survivor and the weak co-op Outbreak series.
The worry is that Operation Raccoon City could fall into the second category. It's solid-looking and has a robust cover system, but it all looks a little generic, with basic third-person shooter combat. The class system could add some depth, however. One player can control enemies for brief periods, for instance, while others are heavily combat-focused.
One thing the game excels at is appealing to long-time Resi fans, with levels set during events that shaped the series' mythology. One early level sees you fighting William Birkin.
