WADs in idGames, ZANDRONUM
There is a dimension, a dimension full of nonsense and surrealism. It is a place where crates are out to kill you, and a place where logic jumps off a bridge. A journey into a wondrous land of ludicrosity, your next stop: Beyond Reality! This WAD is playable on zdoom, skulltag, and zandronum, OpenGL is recommended to remove palette issues on some textures.
Friendly Cooperatives 3
The third installment of the Friendly Cooperatives series with simulated players that have even better A.I. than the previous versions. Also this new version gives you more control over the size of the team and who you want helping you. Comes with a manual so those who are clueless how to use it can now see it visually.
You know Doom, it is always the same, get some weapons, infiltrate the destroyed UAC base or demon hive, kill all the monsters and hellspawn and find the exit switch. This was Doom... until now: Stronghold is a mixture of Unreal Tournament's Assault mode and Skulltag's Invasion mode. Defend your Stronghold against hundreds of monsters, divided into several waves. Earn points, get rewards between waves and let no single enemy pass!
Super Mario Bros Deathmatch
A project brought to you by the ZDoom and Skulltag community, this is deathmatch in the Mushroom kingdom, an additional weapon mod was planned and contstructed that contained weapons such as Racoon and FireFlower morph pickups, but due to Skulltag's currect limited morph support and bugginess it has been scrapped, which is a real shame. MDM04 has been excluded from the maplist because it has awful gameplay value, but you can still warp to it if you are curious.
