Played surprisingly well for the first co-op Resident Evil game. Controls are just as satisfying as RE4, but lacking some of the enemy variety.
Co-op ads so much to a game. The inventory integration was handled well and still feels RE-y.
The general tone is not nearly as strong as RE4, as seen in more bombastic action scenes, a first act entirely during the day, and turning Chris even more boring, somehow. A far cry from Leon Kennedy.
I personally love Wesker in this game. The story doesn't provide a ton of substance for his motivation, but revelations about his past are interesting if you enjoy the greater Resident Evil narrative.
Solid overall package. If nothing was a step down from RE4 this would be one of the best Resident Evil games.
