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. But not only the classics! The editor shall become a key development tool for the Volatile3D II engine, that is why its second name is Volatile Development Kit.
Jackhammer is being developed since August 2013, that means the editor is very young. But the team of professional programmers and testers is ready to present the public alpha within four months. Despite not all the functions being implemented, not all the planned games being supported and only a small extent of the new ideas being realized, today you are able to download, install and evaluate Jackhammer in action. Please don't forget that alpha is the first, quite a raw version, and 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 Jackhammer with financial support, donating funds for the further development.
We are pleased to see you amongst the Jackhammer users!
