You are an old-school level designer, or just decided to become one, but tired of limitations of Valve Hammer Editor? Radiant seems to be too complex and unusual? Wanna use new cool features? Seeking for a user-friendly level editor for Half-Life, Quake, Quake II, or Quake III? It's time to test our new level editor, J.A.C.K., previously known as Jackhammer, in action! News, updates, tutorials, discussions and much more.
With the next public release you'll be able to make maps for Gunman Chronicles - a nice sci-fi game on Goldsrc engine by Rewolf Software. There is already a 2-map ADDON created in Jackhammer: grab and enjoy! Link: Moddb.com
