Dungeon Fighter might hit steam.

Nexon's Press FTP was modified on 6/22
There's a steam folder now, and the three subfolders are Combat Arms, Vindictus (Which recently launched on steam), and Dungeon Fighter

In the folders, are files that fit the layout of the steam pages, as in, a large game icon, and a preview picture.

Wonder if this means folks will be able to spend funds from their steam wallet on NX.
Might be an interesting direction for the game to take. Inventory integration mayhaps?

Steam funds -> NX. Maybe. Nexon would have to cut some sort of deal with Valve though. It'd be interesting though.
Inventory integration: Don't count on it. That'd probably require a whole lot more work than Nexon would want to do.
