Outdoor levels

Todo: If anyone would like to participate in creating this that would be nice, because I would like to see different ways of making outdoor levels.

Outdoor levels in GoldSrc refers to levels that feature outdoor environments and terrain. Unlike Source Hammer Editor, which features the Displacement Tool, terrain must be created manually for levels, often employing the use of the Vertex Tool.
