A recent update to Dungeon Hunter 4 has added a rich guild system so you can team up with buddies, hack and slash your way co-operatively through fantastic quests, earn exclusive rewards, and a revamped chat system for coordinating. There's also a new gambling section called the Wheel of Fate, if you want to try your luck.
As always, Dungeon Hunter is a fantasy style action-RPG where players chose their class, level up, pick abilities to improve, lay waste to all sorts of ne'er-do-wells, and rack up the loot afterwards. Be warned that there are plenty of freemium tropes here, but there's more than enough eye candy to make plenty of players overlook the issue. Competitive online multiplayer and hardware controller support make for a fun time all around.
How many of you guys have put time into the Dungeon Hunter series? Have any of you been hankering for a better grouping system?
