Capcom has released the Dead Rising 2
Ninja Theme pack to PSN and XBL, and it will give Chuck some new powers. With the ninja pack, he gets a stealth mode that helps him evade zombies and make him harder to detect. Also, all sword-type weapons will have their attacks increased, stackable items and throwing items will see increased damage and Chuck will gain special attacks. You can pick up the Ninja Theme pack for a cool $1.99 or 160 MS points.
