Vindictus

A hack-n-slash MMORPG with a storyline revolving around Celtic mythology. Choose from five characters – Lann (DPS warrior), Fiona (paladin), Evie (mage/support), Karok (tank), and Kai (archer) -- and hack away at the well detailed world of Vindictus. The Source engine, also used for Half-life 2, allows you to interact with the environment on a greater scale than in virtually any other MMORPG. The game’s combat system is the cherry on the pie: you can slash your opponents with practically anything, be it the kettle on the floor, the monster’s helmet, or the broom which just happens to be lying around. Instance-based play (the cities act as hubs and trade centers) offers solo and co-op opportunities; PvP is also available, both in dungeons and arenas.
