TRIGLAV is an online action RPG. Objective of the game is simply to reach the top of TRIGLAV Tower. For that objective, each player character can use combat skill, special ability, and many items. You can play TRIGLAV for free. The game was written entirely in DHTML/Javascript and will run in IE only (v5.5+), Mac users can't play it.
That looks and plays a lot like Blizzard's Diablo game.
