Vandomizer is a "vanilla" randomizer for GZDoom. It randomizes the spawns in Doom maps without adding any extra enemies or items. The mod offers three different randomization modes with varying degrees of chaos.
I really love this randomizer!
It creates insane scenarios while mantaining the vanilla gameplay, so for those familiar with Doom/Doom II will know immediately what chaos is going to happen.
More options for randomization would be nice, and it can break some maps by putting solid decorations in some narrow places, but after all is really fun!
