Jackhammer is a brand new level editor for games with a quake-style
BSP architecture. 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. Despite Quake and
Half-Life having been released a long time ago, the large community have
arisen around, still developing mods and games on their bases. However
the existing editors suffer from fundamental disadvantages their users
are well familiar with. Jackhammer does aspire to be the universal level
design tool for classic games.
