This is another large file I found on the Internet Archive an year ago, and decided to archive here, It's an CD called DooM Heaven II:For DooM II, An 1995 "shareware" release CD, It contains many wads for DooM II from deathmatch levels and single levels to mini episodes and full fledged Megawads. This file is not by me and I do not take credit for it either, All credits of each wad and the editors included are in the file.
To run an DooM 2 wad, You can either use the DooM95 Launcher from the Collector's edition of DooM or use an source port.
To run an DooM 2 wad on source port, Drag the wad you have to the source port launcher, And selected the DooM 2 wad and run the wad with it, This will activate it for use in game
To run an DooM 2 wad on the DooM95 launcher, Replace the doom 2 wad in the wads location with the wad's name and run the game to activate the wad.
