I've been thinking that most of the characters in Battle Royale have mash-up levels, but what about Sir Daniel Forteque?! A cool level with zombies, night creatures and crypts aren't enough good ideas for an amazing level design taking these elements? Also, what about a mash-up level with Shadow of the Colossus and Journey? >w< i'm so excited for the upcoming new DLC that's coming soon!
Location: The Museum
The **bleep** you monster from DmC will appear and fight the dinosaur boss from MediEvil 2.
Location: The Graveyard
The Tartarus will appear in the background and zombies will fight the shadows.
Also, I'd like to see MediEvil be the invading mash up for a Fat Princess stage.
