The tool has a classic Windows interface which is divided into four display sections, each showing a different map layer of the game you want to edit. To be able to use this tool, you need to have a knowledge of software designing and experience in designing game levels. This is an official map creation software for the popular games. The game engine is the engine that popular games like Half Life and Counter Strike used to run on. The software is included in the Source SDK which is made available for everyone who purchases a Valve game developed using the Source Engine that is not a mod.
The tool enables you to create geometry, script events in maps, manipulate objects and place them in the game world. You can ensure that the object or entity you’re placing in the game world is supported by both Source and Goldsource engine or it could lead to error.
It also allows you to compile the maps you created by passing them through three different executable programs which render the geometry, the geometry destination, and lighting.
Overall, the tool allows you to create new game levels for the earlier mentioned games, including Quake and Quake II.
