I don't know who started the "if you open a chest, we wont get good loot at the boss", but I opened every single chest in biosphere and got 3 recipies in an hour....Also sick and tired of getting booted from Reactor Core for opening chest. I opened every single chest and let the hostages die..guess what..? Pink Razer, pink nova dropped... So please stop booting people for this....Those that believe in this myth have been decieved and should re-evaluate how they play this game....Think about it, why would there even be the extra rooms and chest if STS didnt want us to open them, DUH! Common sense people
