Terraria devs just snuck in Linux beta support (and OS X).

The 1.3.0.7 release is an open beta test of the Mac and Linux versions of Terraria. It contains no game content changes, only modifications to the game engine for compatibility with Mac and Linux systems. As such, this release has no formal changelog.

You have to be subscribed to Steam's beta opt-in but it looks like it might work. I'll update more later.

One thing I'm not super happy about is the location they store save game data. It's under ~/My Games, which is something of an anti-pattern in Linux. It'd be better off going into a ~/.terraria directory (or similar).

Fortunately, they have a forum dedicated to this. I might make a note about it.
