Alpha Protocol is one of Sega's big fall/holiday 2009 titles and the modern day super spy action-RPG from developer Obsidian Entertainment should be something to look forward to. Now folks who download and buy their games via Valve's Steam service have an even nicer deal to look forward to.

If you put your money down for Alpha Protocol before the game is released in October on Steam you can download and play the Sega-published 2008 sci-fi action-RPG Space Siege right now. The title, from developer Gas Powered Games, normally costs $19.99 via Steam so this is an unusually nice free game deal from the service.
