Valiant

Valiant is a 32-map megawad created by Paul "skillsaw" DeBruyne in 2015.

Valiant is a MBF megawad for Doom II featuring 32 new maps spanning 5 themed episodes. Each map is designed to be played from a pistol start, but some effort has been made to support continuous play as well.

Additionally, Valiant includes a number of new monsters and weapons implemented through an extensive MBF format DeHackEd patch. As a result, Valiant is not compatible with gameplay mods, and can only be played in ports with full MBF DeHackEd support. At present, these include ZDoom, GZDoom, PrBoom-plus (complevel 11), and Eternity. Zandronum is also supported through DECORATE.
