J.A.C.K.

What is J.A.C.K.?

J.A.C.K. (Just Another Creation Kit; previously known as 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. J.A.C.K. does aspire to be the universal level design tool for classic games. But not only the classics! The editor evolves, there are plans to support Source Engine and Unity.
