I was really hoping DOOM 2016 would include a reference to Daisy somewhere! What’s also great is Doomguy’s “phone number” is the release date of the original game. The level designer who did this is awesome.
Good to know the best pet rabbit a demon slaying Space Marine could ever ask for hasn’t been forgotten.
