Simply a must have for any Wii owner.
The game is challenging, each chapter is divided up to three subchapters, each lasts about 15-30 minutes depending on how well you play. Notes and documents are scattered around the map, finding them increases your score, as well as shooting zombies in critical locations (which isn't easy.)
Each chapter also has bonus chapters that deal with other characters in the game, like Wesker, Ada, and Hunk apparently (I haven't gotten to Hunk yet.)
The game is challenging and fun, a must buy... or at least rent it... you shouldn't be disappointed.
