Mine's glitched and I have no keys anymore but can still loot the chest whenever. It's been the same since last night.
Trying not to abuse it though because it'd end up ruining the game for me to have a chest that always gives me nice stuff lol --- With the advent of online games came the creation of the 10th level of Hell, reserved solely for tea-baggers.
I have heard that you can (so far) get 2 legit keys. I have also heard of some people getting 3 or 4 just from doing what would normally net you 2 keys. Maybe it's just a little glitchy since the servers are probably a little overloaded with launch being today.
Got a good bit of money from it at level 9. Still works now, just did it a second ago seeing if rocket will pop up in it. --- With the advent of online games came the creation of the 10th level of Hell, reserved solely for tea-baggers.
