Quake is only $2.50 on Steam right now, so if you’re looking for a reason to dip back into another one of id Software’s all-time classics, now’s the time.

Installing the new levels is pretty simple, too.

1. Extract the RAR file into Quake’s main directory as a folder called dopa.
   
2. Launch the dopa executable inside the dopa folder.
   
3. Start a new single player game.
   

Dopa!

Bethesda hinted towards at Wolfenstein game during E3, possibly called The New Colossus, but I wouldn’t be opposed to them working on Quake, either.
