Freedoom 0.6 - 0.9

[XK 47]

Most of it pre 0.10 was very good. Hellonearthstarterpack.wad players may recognize some of the maps because, they are the source maps. The chaingun texture pre 0.10 looks like an actual chaingun and not a single barrel with holes connected to a cylinder with holes. Most of the other weapon sprites were really good. Except the shotgun. That can go to Hell as ID Software has once said. For the monster sprites, eh good enough. Some sprites like the imp are better made in 0.6 - 0.9 than in 0.10. Other sprites look even worse than what they are now in 0.10. Overall good IWAD.

Also, there was the fact that there was stolen copyrighted content in the earliest versions (those aren't archived for that reason)
