Exclusive content based around the NiGHTS Into Dreams series is hitting the Wii U version.
Sonic Lost World on the Wii U will launch with a special Deadly Six Edition that includes bonus content themed around the NiGHTS Into Dreams series.
A trailer indicates that bonus boss fights in the style of NiGHTS will be included. It is not yet known how this edition will be available, be it through pre-orders, or first print copies.
So far the Deadly Six Edition has only been announced for Europe, but a North American announcement is very likely.
