Jackhammer is a brand new level editor for games with a quake-style BSP architecture (Half-Life, Quake, Quake II, Quake III, Gunman Chronicles). The aim is to develop a convenient cross-platform tool capable of incorporating the best features of existing editors, such as Valve Hammer Editor, Q3Radiant and others. The list of supported games will be extended. Today we finally moved to beta status, which means that the editor became more reliable. Remember that your feedback is always welcome!
