It seems to be popping up lately, I dunno if its a glitch or what but people are increasingly hiding inside the blue box (there's three - a single one and two stacked) near the left entrance to the area below the train. I don't know if there much of an advantage to this. Except for campers with a silent sniper.
My son (a10 year old [thats his nick - not just how old he is]) figured out how ppl are doing it, which I wont share with you guys, but its easy. He discovered it after a player named Justin basically advertised it by going there as the enemy hero.
Has anybody else seen this? And will it become a problem?
