A little heads-up for players of https://www.quaddicted.com/reviews/ad_v1_42final.html:
A second patch has been released that contains bug fixes and additional features. Most importantly, it also includes two new levels by https://www.quaddicted.com/reviews/?filtered=sock and https://www.quaddicted.com/reviews/?filtered=Scampie: a remix/remake of Quake’s E2M2 and one of Doom’s E1M1. This new patch makes the first one obsolete.
