Yes; whooping and other celebratory noises commence, Dredmor has had a expansion-DLC.
So of course I downloaded it the instant I saw it on Steam and I’ve been playing it since (although it wasn’t available instantly for some reason due to some technical hoo-hah, it’s all fixed and all fine now).
New skills seem to be a decent mix, there appear to be a fair amount more enemies (even on the first floor), I like the more expanded inventory system (i.e. belts, trousers and gloves as well as what was available before), and I’ve already managed to be whisked off to a strange dimension to die at the hands of a demonic carrot.
Anyhow, expect a playthrough tomorrow.
