Relic - course in sky mod?

[The Legend]

I recall seeing a mod where someone put sniper tower bases all over the sky in relic making a obstical course above and around the map with slides and cork screws and lots of jumping between them... and if you fell off over water you died and start over.

But... i cant find anywhere to download the patch for relic for it... or any mention of it. If this mod sounds familier could someone please tell me what this mod is called.

A LINK WOULD OWN

I want to add on to this map but i need to find where to get it.

Help is apreciated GREATLY
