Over at Andy Leaver's Doom Projects you can check out a couple screenies from map27 of the author's work in progress Pir 2. Says Andy:
The map is going to be small but hard. Pir 2 is going to finsihed real soon..only maps left are 27 28 29 30 31 32 and most of those are already started. More screenies coming soon.
So be on the lookout, jerk stores.
