Deep within the Nevada desert is a secretive military installation housing some of the most modern aircraft, weapons, and possibly aliens? This map was created by bunglist, and was released on Facepunch a few days ago. This is definitely worth taking a gander at.

About the Map:

I took the idea for the basic layout from the “real” Area 51 in the Nevada desert using Google Maps (so secret it’s on satellite view!) and from various websites dedicated to the base. Intended as a sandbox build map with something for everybody and designed for long-term use on busy servers, after 6 months of development and many betas tested by Bunglist Build regulars (thanks guys!) we are ready to release this map to the public. Now available for download now is a “Release Candidate” version, any problems discovered in this version will be fixed before the final release, which will be posted here when it is done. If you want to see map now the latest version is up on our server, drop in and have a look around!

Features:

• Does not require any additional games – no need for HL2 Episode 1, Episode 2 or CounterStrike Source
• All hangars and popular build zones are Area Portalled for reduced-lag building
• 3D skybox, maximum Hammer size and 16th scale
• Optimized using every technique covered on the Source SDK developer wiki (compiles in about 10 minutes)

• Missile silo with concealed launch bay doors, control room and booster pads for “helping” things into the sky
