Art of Ascension is a free RPG modification for Half-Life 2. Art of Ascension combines the spirit of online role playing games with the faster battling pace of classical first-person shooters. Players increase their character's level and enhance their abilities through the course of playing. In Art of Ascension emphasis is placed on game play, balance, and battling.
All your characters are distributed between all servers and linked to your steamID and character's name, and the name is reserved for you on all servers. This mod is still in beta, with some abilities not implemented yet (only a few), and skill rebalances are on going.
Note: this mod is a pseudo-sequal to a popular Quake 2 mod called "King of the Server", made by the same team, using some of the same ideas.
