Above and Beyond Technologies reported that it improved the quality of life for Rogue characters through a number of changes. The thievery mechanic got an upgrade, pick-pocketing got several missions, and containers got stubbornly locked. As an aside, there are six stealthed Rogues in the above picture. See if you can spot them!
Other changes to the game for the second alpha test include mission chains, random missions, 70 new crafting recipes, two new generic den types, and an overhaul of the reputation system.
