Hey. I know of this exploit, but I have seen something pretty crazy in coagulation ctf. None of our team knew how it was done, and it was during a big team battle. The guy must have been doing it every game he played, because he was a level 16 in big team battle (Yeah, what the hell).
It was a one flag game, a few were inside the base, the rest of us were around the base, ontop/outside. Out of nowhere the flag is gone and everyone is looking for it frantically. 15 seconds later, flag captured, round over.
We play our offense round, dont think we capped it... Anyway, final round we all wait in the base, we have one guy below keeping an eye out for a warthog below the base (we thought maybe they grabbed it from below and didnt notice).
Flag taken, no warthog, no enemies in sight. I run to the teleporter, scope and see a warthog coming out of the canyon with warthog carrier in the side seat, driving towards their base.
After the game, the other team leaves all together without a word (they must have all been one party). We all reported the one guy with cheating feedback, if anyone is interested i can look up the stats of the game. You see an arrow of where the flag goes, from inside our base to their canyon directly, less than 1 second (each tick represents a second, only one tick)
