One of the most highly anticipated releases of 1997, HeXen II was the first game from an outside developer to ship with Quake engine technology. The game featured four single player hubs and deathmatch capabilities for 16 players while simultaneously offering four character classes, each with four weapons with dual fire modes for a total of 32 unique weapon effects. In addition, HeXen II was the first 3-D shooter to feature transparent water effects in both hardware and software rendering modes and one of the only fully 3-D games to feature single player cooperative gameplay. Modified much like its original this game has stood the test of time and has quite a few nifty mods to show for it
J.A.C.K. (previously known as 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. 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.
