What Could Have Been: As mentioned on the main page, the earliest idea for this game was to be an adult-oriented spin-off of Ubi's own Rabbids series for the PS3 and Xbox 360. When development switched to the Wii U it was then renamed "Killer Freaks From Outer Space," and was to be a tongue-and-cheek action comedy/fast paced FPS where the protagonist was a foul mouthed Englishman fighting aliens (which still still looked a lot like freaky versions of the Rabbids) that invaded London (footage of this build was shown off at E3 2011). The reason why it was changed from a fast paced shooter to a a slower paced survival-horror game (according to Word of God) was because the original idea would have made using the Game Pad in the heat of battle too much of a distraction, so slowing things down made using the Pad less distracting, while still keeping things tense by not pausing the on-screen action.
Development Gag: The original "Killer Rabbids/Freaks From Outer Space" idea is referenced in the supermarket area. Stuffed animals of the enemies from the original idea are found on some of the store shelves.
