Kill the Mutant Rancor siege map.
This was my first map.

For the record: Rancor won't attack you in atst and it's easier to kill it with an e-11,
The game won't tell you if the rancor is under attack, but everything else should be fine.

The file is zip, so you have to unzip the pk3 to your base folder.

You can modify it as long you give me proper credit.
