According to Gamesta.com, Square Enix has added Tomb Raider: Underworld to the growing list of free titles on their browser service Core Online. If you can stomach an ad every now and then, you can play the entire thing for free.
As with all titles on Core Online, players can stream the game freely for the small setback at the hand of periodic advertisements that pop on the screen. People that do not want to see ads appear, usually every 20 minutes or so, can choose to pay a small fee to make them disappear. In this case, it costs $9.99 to remove publicity. Tomb Raider: Underworld will take Lara’s adventure through mostly maritime themed levels, such as the coasts of Thailand and the Arctic Sea.
