Often regarded as one of the most influential shooters ever developed, Deus Ex blended first-person shooter gameplay with a branching, complicated storyline, upgradable stats and skills and extensive character interaction. A sequel, Deus Ex: Invisible War, was released in late 2003.
The title will be playable via the service's free-to-download launcher program, which allows users to browse and download a variety of PC and emulated console games. Those players who don't shell out the $9.95 per month for the "Gold"-level subscription can expect a 15 second video advertisement to air before each play.
In addition to Deus Ex, GameTap also offers Ion Storm's Thief: Deadly Shadows and Doublefine's Psychonauts among some 120 other titles in its free game roster.
