URE2020: Unexpected Retro Experience

URE2020: Unexpected Retro Experience is an episode replacement for the Ultimate Doom, released on April 15, 2021 by Zylinderkatze. Originally planned as a full four episodes replacement, in its current state this WAD contains only a re-imagined version of the first Doom episode - Knee-Deep in the Dead. It was named as one of the runners-up at the 2021 Cacowards. The second episode is in active development as of February 2023.
