Enclave by Starbreeze - Ogier level editor

Starbreeze is proud to present Ogier, a tool for creating levels in brush-based
engines. Ogier has been in development within Starbreeze since September 1998.
It was released to the public for in January 2004 as a Christmas present for
the persons out there that wanted to build levels for Enclave.

Ogier is a part of the Starbreeze Engine, and has support for editing levels
for games using that engine. Currently, you can download editing support for
the Enclave. Ogier can also export and import the .map file format and load
.wad textures, so creating levels for games using these file-formats is a
possibility. Included in the Ogier installer is a basic setup for editing Quake
1 levels, but it´s pretty much untested.
