Valve just announced that Rusty Hearts, the Action-MMORPG developed by Stairway Games and published by perfect World Entertainment, joined the Steam Free to Play line up.

This means that, if you have a steam account, you can just go here and click on "Install game", and you'll be able to enjoy all of Rusty Hearts' anime-style action effortlessly and (of course)  for free. Free stuff is always good, even if it tempts you to spend half your monthly wages in the cash shop.
