Comment: "Simulacrum is a set of 32 maps in MBF21 format by @muumi and @myolden. This set starts modestly but steadily climbs into challenge and slaughter territory in the later maps. Difficulties and Coop are implemented. Target source port is DSDA-Doom, your mileage may vary in other ports. No jumping/crouching.". Started in January 2023, now we see a release for this megawad.UPDATE 2024-07-01: Updated to RC3.
