It's funny because back in the day of Planetside the GM's would occasionally pull the same kind of stunts that have been happening in DayZ, and that was an MMO. :P Drop a meteor shower on a heavily populated battle zone and wipe out everyone that wasn't inside a building, or play around in one of the sanctuaries throwing players up into the air or stacking tall towers of vehicles and placing players up at the top. Of course those were always a blast and didn't spoil the fun. And now that I'm done reminiscing... yeah been a lot of hacking going on, people trying to ruin everyone's fun.
