By the way, many of the Qtest sprites are actually poorly converted Doom sprites (hence the weird colors). The Scrag's projectile, for example, is the projectile of the Cacodemon from Doom. The teleport sprite is the same too.

I also think the Qtest Water/Slime/Lava textures were taken straight out of Doom as well.
