DOOM: 17 Easter Eggs, Secrets & References You Must Find

13. Quake's Logo

One of the first little nods I found to iD's wider world of incredible games, Quake's symbol is actually available as a pattern option for your armour.

You'll unlock it as you progress through the multiplayer component - either standard deathmatches or SnapMap - and it can then be applied across all skins. Could this mean Quake is next up for Bethesda to revive, following Wolfenstein and DOOM within only the last couple of years?

Here's hoping!
