This is the first chapter of SOOM, but it is not the final version, it is in fact a beta of a game that will come later; for this reason there are only 3 levels inside.
Easily one of the most fun mods I've played in a while.I liked the use of assets given,the level design, and overall effort put into this otherwise short mod.I really do hope that you continue to work on this, I would love to see how it is when completed.
