Knee-Deep in the Dead

Knee-Deep in the Dead is the first episode in Doom/Ultimate Doom, and the only episode in the shareware version. The episode takes place in the UAC installations on Phobos, one of the moons of Mars.

Designed mainly by John Romero, the levels have a unique graphical style characterized by extensive use of STAR textures, large amounts of highly saturated brown and green in general, and a misty, mountainous skyline.

Because of Episode 1's singular inclusion in the Doom shareware version, as well as John Romero's skilled level design, the Episode 1 style levels have become one of the most popular and easily recognizable Doom design themes. Fan-made levels utilizing exclusively Episode 1 textures, and often emulating Episode 1's play style, are commonly referred to as techbase levels.
