Q3DM10: The Nameless Place

Q3DM10: The Nameless Place is the fourteenth map of Quake 3 Arena.

The Map
It appears to be a factory or an abandoned space installation. A special feature within this map is a generator of sorts, which boosts players' health and armor as long as they stand inside it. Staying there for too long is ill-advised, however, as there are numerous ways leading to the generator, leaving players vulnerable to attack.

Trivia
This map uses the skybox of the space-themed levels in Quake 2 and could thus represent a space facility (possibly of Strogg origin).
