Planet Calypso updated to version 2010|01 (their new system uses the year and update number, rather than version number) but they've also had a small volcanic eruption that's changed part of the map. Blizzard, eat your cataclysmic heart out.
While the newly re-terraformed area of Cyclops has been visually improved by the team and patched in under the 'guise of a volcanic explosion, the version update also brings the anticipated mission system to Calypso.
The mission system, which is in a public beta, more or less, is only currently offering 5 tutorial missions to newbies landing on Calypso for the first time. Once you complete those five missions, be sure to offer your feedback in the survey that pops up at the end. That information will be used to make more missions for higher level players, so don't be stingy!
Also, there's fish. Remember those fish we showed last time? Yeah, those fish. If you value your ankles, you'll watch where you swim.
