(Sega AM1's universe)
While the gameplay and bonus content for The House of the Dead 2 is the same as the original Dreamcast and PC ports,The House of the Dead III includes a new unlockable Extreme Mode, with tougher enemies and a smaller blast radius on the shotgun. In addition, weapons can now be used as a melee attack to block enemy blows. The melee attack requires the player to reload after each use. The port is officially taken from the Xbox versions.
According to Sega director Emiko Sunaga, the original 1996 game The House of the Dead was excluded from the compilation because it had a "significant visual gap" and needed reworking for the Wii. The House of the Dead 4 was also absent because at the time of 2 & 3's release, it was still available in arcades.
The development team concluded that because The House of the Dead 2 and III arcade cabinets were getting rarer, and that these games were the most "popular" and "unique", it made the most sense including them in the compilation.

And if all that isn’t scary enough, the unlockable Extreme Mode will test even the best shots, with quicker enemies and a smaller bullet blast radius from your weapons making the action even more frantic.”

House of the Dead 2 is a simple move over from DC, and it looks and runs just like it did a decade ago, while House of the Dead 3 is a port from Xbox...”
