Here is the mappack for Hellion with the XTREME LFX content! Download the rar file and unzip the contents of the rar file and copy it into the Hellion folder, overwriting what's there. Let me know if it doesn't work.
Thanks to: AznChipmunk for the cool looking level.

To access the Rad Sunglasses map go to the pool in the lower right section of Salidar and inspect the waterfall. There is an inscription that you need to decipher and the way to Rad Sunglasses castle will be unlocked.
