And that was EA's doing there. However...not all's lost. They DO know about Linux and I've been told by a good source in EA's support group several titles that're known to properly work with WINE on Linux and they'd try to work with you at least a little bit if you ran afoul of a problem with it.
If you bought this game intending to play it on Llunx you should sue Epic games. They promised that a Linux client was coming and urged people to buy the windows versions in the meantime. That is just dirty. The Linux community really needs to stick it to lying companies that give us the shaft or we will always have a crappy selection when it comes to games. At a minimum epic should be boycotted.
