First you must acquire a V3S, try and have a passenger so you have twice the odds and a witness regarding your characters visible state. Then find yourself a hill (this was capture south of Berez and I imagine it works best with a rise in terrain as your target) and launch off it. The V3S should sink below the ground while your player cam rests on the ground. Now this is where Camrun (the ZAP member recording) relogs to escape the bug, but Mordon (also ZAP) gets out of the V3S.

In doing so he is left (until relog) able to move and harm players while remaining unseen/untouchable. He was not able to interact with items on the ground or in the vicinity.

This was the first time I've heard of it as it was considered classified by those in channel at the time. I've been told this is the 2nd of 3 times it was attempted and each time they were able to recreate it. I believe you just need the right hill/speed.

The 1st time this happened (again before the footage above) they both jumped out of the V3S and were invisible (to each other) before relog. So this time they wanted to see the extent of this exploit and record it in order to submit a report.
