Steam for Linux is a certainty, but a list of official supported games still hasn’t been made available. Even so, gamers always found a way of getting this kind of information ahead of time, and this situation is no different.

Steam is the client for Valve’s digital distribution platform and so far it was only available for the Windows and Mac OS platforms.

Valve has made a lot of gamers happy by announcing that the client will also be launched on Linux, more specifically for Ubuntu 12.04.1 LTS, but at the same time they didn’t provide any clue about what games will be available at launch.

Lucky for us, there are a lot of companies out there that saw the advantages of a new platform and made the move to Linux.

Beside a swath of new games we announced in the last couple of weeks, three more interesting titles have made their appearance.

The first one is Cave Story+, an amazing indie game that features a completely original storyline wrapped with personality, mystery and hours of fast-paced fun. Cave Story is an action-adventure game from the acclaimed independent designer, Daisuke Amaya, or Pixel to his fans.

The Book of Unwritten Tales is the second game announced for Linux. It’s a point and click mixed with the RPG genre that provides 20 hours of gameplay in a massive game world with detailed graphics.

The third game is Defender's Quest: Valley of the Forgotten – a fun, fast-paced Tower Defense / RPG that cuts out the fluff. Surprisingly enough, the game is not yet on Steam and perhaps it will make its debut alongside Steam for Linux

Our information is taken from the CDR database and by no means is it completely certain. So far, it was confirmed every time, but you should still be a little skeptical.

CDR Database is a record of data that describes every Steam game and subscription provided by Valve for the Steam service. Usually, the new entries in the Steam database are firstly visible in the CDR Database before their official launch.
