Strain is a 32-level partial conversion for Doom II released in 1997 by the Alpha Dog Alliance. It features nine new or modified monsters through the use of DeHackEd, modified weapons, and a soundtrack written by David "Tolwyn" Shaw, Mark Klem, and Jon Landis. The project had a sporadic development history, exceeding a year due to cyclical interest and disinterest[1].
