One map by Sneezy McGlassFace. Limit-removing vanilla, slaughter, 3 textures and 2 flats. You can get it here.
I played this this evening after we had a conversation about what different people want out of playtesting, and also some stuff about how glides work. This map is wood, stone, lava, and rock, with a solid helping of BFG spam, revenant herding, and rocket launcher vs imp wall confetti. You should try it if you too enjoy some of the staples of slaughter. :)
