Quake: Soul of Evil

Old two-episode pack from 2002.
Two episodes! "Soul Of Evil is a primarily single-player Quake game, although it also supports deathmatch, cooperative, arena mode (a new type of gameplay), as well as bot matches."

Two excellent Wizard-style SP episodes with modified and new monsters, many custom textures, and seven additional deathmatch maps.

No doubt one of Dustin "Tronyn" Geeraert's best mapping expositions, especially for 2002.
