Stronghold: On the Edge of Chaos

Stronghold: On the Egde of Chaos is a Doom megawad, created by Daniel "Tormentor667" Gimmer and his team at DRD Team and Realm 667. It requires GZDoom or Skulltag to run. Supports both singleplayer and multiplayer. There were two release candidate versions in August 15 and October 15 respectively, with the final release expecting to come in November 1, 2010.

Official description:

''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! ''

Stronghold is a dooming experience that's very different from what usual Doomers might have played so far, and it really deserves a try, especially the multiplayer coop mode for which the team have worked so hard to balance it. The game is one huge hub with 35 different Stronghold UAC bases that players need to defend, where there are different goals to achieve (e.g. let no single enemy pass the deadline or defend a powercore agains the demons). For support, there is a huge arsenal of weapons and powerup items players can collect and/or buy in the interactive intermission base from where they start their missions. The new approach towards the legions of demons and also the countless gimmicks, specials and easter eggs will make up for a very unique Dooming experience.

Features:
 * 35 new maps (+4 secret maps)
 * 18 powerful weapons
 * 20 different powerups
 * 30 additional new monsters (in addition to original ones)
 * Several different game modes (Deadline, Core, Limit and more...)
 * Full multiplayer support with Skulltag
 * Earn credits for killing demons!
 * Dynamic skill for all skill settings and player counts
 * Hub system with several tiers to battle through
 * Shop system with countless items to buy
 * Full soundtrack with exclusive music and songs
 * And many more thing to discover!

Editing
Stronghold also supports user-made custom map creation. Doom Builder 2 is recommended for map editing for Stronghold, as it has more features than Doom Builder 1.
