This add-on was intended to play Goldeneye Doom: Reloaded Maps on Brutal Doom V21
Still only 3 Maps available:
It replaces all Goldeneye Weapon Types with Brutal Doom Weapon Types.
The Runway Map also has the update. Now, you can use a Tank (yes, a TANK!!).
Requires Brutal Doom V21 to plays. Here the links: Moddb.com
