Starting today at 11 a.m. ET and running until Monday, May 30 at 3 a.m. ET, Crysis 2 players will gain double the usual amount of experience for their online skirmishes. We're sure that's an attractive offer for the game's more ambitious players, but given the volatile nature of these power-ups, we ask that everyone boost their characters at a steady, healthy rate. We don't want to deal with a Tetsuo-esque dude-explosion situation over here.
