INCUBIS
A very late post i know, there are alot of map exploits in the DC MoD as i am sure you might be or not be aware of. The image you show there is not a hack, its a map exploit to get under the floor. We are very vidulant in our team in spotting these and we ban the player for ever on our server after taking a SS and mentioning they have been caught.
The example you show is not a PB hack its a local map exploit really, just stay away from their server as there are plenty of other servers out there where players play this game for fun without any cheating or map exploits in use.
