WADs in idGames, 2012, PWAD
Strife: Absolute Order
You wanted it, now you've got it, a 6 map hub for Strife. Requires a Zdoom compatible source port. A rough story? Well ok. Despite the main threat of the order being defeated, there are many other towns still under their fragmented rule. The front now has the resources to send agents to these outward places and attempt to destroy what's left of the tyranny. You have arrived in the small town of Sweetwater, where what few people survive live a near meaningless life that is under constant threat.
Community Chest 4
The fourth installment of the series, Community Chest 4 boasts 32 maps made by 20 different authors from the Doom community. After four years of work, they have been made available for your enjoyment. Included in this package is the base resource WAD compiled for the project, which can be found in cc4-tex.zip. It may be a good starting point if you need a large, varied, and meticulously organized texture WAD for your project!
Base Ganymede: Complete
A 3 episode vanilla megawad for Doom 1 containing a total of 27 maps. Set on one of Jupiter's moons called Ganymede, this wad should provide a challenge for a wide variety of skill levels ranging from the humble newbie to veteran speedrunner. Each episode has it's own progression rather than the usual base -> hellbase -> hell.
Doom the Way id Did
"At some point in time I got the idea that it would be really fun if John Romero dusted off the ol' doom editor and made another map for Doom episode 1 for old time's sake. He once replied to an email saying 'maybe I will!' but never did get around to it as far as I know. This project asks the contributors to carefully study the original maps and try to make them as John Romero and Sandy Petersen did.
