House of the Dead: Overkill details from Bradley:
- The game is on-rails (o rly?)
- Enemies will have point-specific damage, meaning you can blow off arms and shoot holes in their guts, much like the series has featured in the past
- The game will support the Zapper
- There will be motion-based controls (shake the Wiimote to get a zombie off you, etc)
- You can perform "combos" which will fill a special gauge and unlock upgrades
- You can switch between two different weapons on the fly
- A special adrenaline gauge will allow you to activate a special power (most likely a bullet time variant)
- The game is running on a new engine built specifically for it
- There will be a co-op mode
