Sandbox 2
Sandbox is the level editor included with the game Crysis that enables the construction of maps and modifications (“mods”) for the CryENGINE 2 3D environment technology.
The editing style is that of the sandbox concept, with the emphasis on large terrains and a free style of mission programming. The editor can also construct indoor settings.
UnrealEd
UnrealEd (UEd for short) is the level editor used to create levels for Unreal. It can also be used for other games in the Unreal series, and games based on the Unreal engine, such as Deus Ex, although it has changed along with the engine for later games. Non-Unreal games use their own version of basically the same program. One of the first companies to do this with first person shooters,[1] all Unreal games on the PC had the level editor included for free, and some third party Unreal engine games did the same with an edited and specialized version. This extended the longevity of the games. Amateur level designers could now create their own levels for the game, providing a near endless amount of additional content for the game. In addition, the built-in scripting language called UnrealScript allowed for editors to customize game content.
Valve Hammer Editor
Valve Hammer Editor, formerly known as Worldcraft and now commonly called Hammer, is Valve Software’s map creation program for their first-person shooter computer game Half-Life and for all of its mods, sequels, and expansions, as well as all games using the Source engine. Old versions of Worldcraft also supported Quake and Quake II. There are currently two versions- version 3.5, a beta version (still available to the public, but no longer in development), which supports only Half-Life and its mods, but can be run without Steam. The current version, version 4.1, supports Half-Life 2 for the Source engine as well as Half-Life, but requires Steam to be operating. It is accessed via a download of the Source SDK.
