J.A.C.K. 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 shall become a key development tool for the Volatile engine, that is why its second name is Volatile Development Kit.

J.A.C.K. is being developed since August 2013. Today our team is ready to present the latest public beta - new version 1.1.1064 (changelog). Despite not all the ideas being implemented and not all the functions being completely error-free, you are already able to download almost fully functional version of the editor, install and evaluate J.A.C.K. in action. Please don't forget that beta may contain some issues. We are interested in a vast testing of the editor and grateful in advance for your comments and suggestions! In addition, you can provide J.A.C.K. with financial support, donating funds for the further development.

We are pleased to see you amongst the J.A.C.K. users!
