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.

Supported Games
  • Half-Life (including mods and Gunman Chronicles)
  • Quake (including mods and some Quake-based games, e.g. Hexen II)
  • Quake II (including mods)
  • Quake III (including mods and idTech3 based games, e.g. Tremulous)

J.A.C.K. is being developed since August 2013. 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.

Also, as -vG- Lemon said:
"Jackhammer is a great editor, and its multi-use ability puts it above par of its competitors (sledge editor, VHE), but I find it's lacking three main things, however.

1) 3D Manipulation of Geometry
In Hammer editor 4.1, pressing 'x' in the 3D view allows you to resize blocks in that window, as well as perform vertex manipulation actions.

2) Copy and pasting onto the mouse location
As it stands now, all pastes seem to go up and to the left of their original copy. To paste directly where the cursor is positioned, both in 3D and in 2D views, would be an incredible boon to mapping efficiency.

3) Prefabs
Simply put, a prefab system similar to "&i" in 4.1

If these were implemented and game support was extended further (To source era games, perhaps?) I'd definitely throw a few bucks this way."
With these features, JACK would be better than Hammer in every way! And with Steamworks, it would be amazing!

If this gets actual Source engine support, I'll gladly buy it!

I'm Fine with Paying for this, just don't make it Cost $42.

I also think that the price i MAY be able to afford is $10. J.A.C.K Is already dependable so it's a sure-buy for me!

J.A.C.K. Would be my main Map Maker if there's .ol (object library) and prefab support. Please add prefab support :steamsad:

Don't worry, for those people who doesn't want to financially thank the author for years of hard work, there always will be a free version available, just like now. Although it will miss some steam-specific features.

Bit f misunderstanding here, I use JACK because it is better than hammer. But If it become paid, I think that I'm gonna get back to hammer.

If you're happy with normal Hammer's feature set, then of course you can use it. :)
