I've had a few requests to release some of the buildings that I'm using for my huge multi-player map that I'm building so I've decided whenever I complete a portion of the map I'll release one of the buildings that will be included in it.
All of these buildings are built with a variation of my Duke pack (no aliens) as to make it more modern and to give more building blocks and it's included in the download so I recommend using it with these models otherwise it will look rather strange.(its 64x64 so you'll need the HD texture pack fix to use it)

The first building that I'm going to release is a hanger that I have made for a military base on the map.

I'm also going to issue a challenge to anyone that will accept it. My usual 11 testers and I managed to hold the building for 1hr and 12min. I want to see how long people can hold the building.

Rules:
defenders have one double chest of supplies and no re-spawns
attackers have no resource and re-spawn limit.
you can destroy blocks but cannot place except for crates.

Additional Notes

If new records are posted they will be repeated at the top of the thread
I'll be only sharing 1 structure at a time so get them if you like them.
