(Youll need a copy of Doom to run GZDoom, too.)
The levels also work as deathmatch maps if you run them in the multiplayer mode.

Happy 30th birthday, DOOM.
I’m grateful to have been a part of this incredible team.
Todays tools are amazing, Romero said inour recent look back at Dooms 30 years.

Im still doing new things.
Happy birthday, Doom.
