Swift Death is an extremely hard megawad, calibrated for speedrunners. I recommanded for novice players to play in "easy" ("Toilet Break", or "Soft Event"). SD is realized in speedmapping sessions, for the most parts of maps. These maps are generally small, and contain on average 75 monsters. They are also compatible for the duel / deathmatch.
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.
