Dubbed 'The Sewers of Dross' and playable only with Gish, the chapter will feature twenty levels that Team Meat says "ramp in difficulty from medium to soul crushing."

It'll arrive with the platformer's upcoming title update, which is being submitted for approval this week and will hopefully be up by November 21, fixing bugs, erasing 0.0 times from leaderboards and adding a new music track called Dr. Fetus's Castle."

Team Meat also teases the four remaining unlockable characters yet to be revealed for the PC edition, saying that "one of them sticks, one of them dashes, one of them changes form and one of them isn't organic." A silhouette of one is also offered, which some note resembles Josef, the star of Amanita Design's Machinarium. Minecraft's Mr. Minecraft and VVVVVV's gravity-flipping Captain Veridian already confirmed for PC.

Team Meat expects to release SMB on PC via Steam in the last week of November. The WiiWare version, however, is in dire straits, but might get a retail release.
