An infection map, based on the colony from Aliens.

This map features basic interlocking and S&Q techniques if you want to forge it.

Aliens move at 150% speed and have normal shield but it doesn't regen. LMS gets 2x overshield, doesn't regen either, and a 10% speed boost.

Aliens have a 75 meter radar range, humans have normal.

A view of a small shed (which may or may not contain some useful goodies) and the APC (a gauss hog)

The sentry gun, Aliens will die if they run down the hallway but the Sentry can't cover the giant vent running across the map.

"We've got 2 pulse rifles with a few grenade launchers, one working flamethrower, that ain't good" Weapons now hidden around the map, as well as the mines.
The grav lift is your "welder" which can be placed in the giant vent, but you have to venture in some to get the best use of it.

The start room still contains the shotgun and welder though.

This room isn't as safe as it appears. If you want that launcher you have to wonder into alien territory.

Inside the giant vent is a "smart gun" but it's far in, worth the risk? it's up to you.

A hiding room in the complex, also shows some of the interlocking I was talking about.

"Complex 2"s generators room now contains the flamethrower.

View of the lookout room which has a sniper in it.

Hudson! Get that door open!

SCREE!!

The main vent. This is the sole reason you shouldn't use the sentry gun and is the main attraction of the map, it's a direct link from the complex (alien spawn room) to the Med Lab (human spawn room). Any alien in here can run through it and kill anyone that doesn't have back up on the sentry.

The complex also has a basement though there's not much in there except a few goodies.

Use with the Aliens game type which you can get here.
