Just play it if you're bored and wanna kill a few minutes. I just made it for practice. I may or may not add onto it, probably not though. This will most likely just be a single map. The music is by Jimmy and the theme is similar to a map I made for the Harvester map pack earlier this year. The one custom monster is an edited Soul Harvester that I was going to use in a singleplayer map pack I wanted to make (a collaboration project) but it never got off the ground.
