Doom 2 map - Xmas Assault on Cyberdemons Skate Rink

A big snow-themed level for Doom 2.
With this wad, I intended to make you utilize some nonlinearity to the order you can take the encounters, as well as better movement than just circle strafing, and that's why everything is so narrow and vertical. There are 5 cyberdemons, arch-viles, chaingunners and reventants, who all are meant to oppress your movement in different ways.
