PC download charts: 'BioShock Infinite'

Pre-orders for the PC version of 'BioShock Infinite' see it charting high on Steam, GameStop Impulse and GamersGate ahead of a March 26 release worldwide.

Each have been offering various pre-order incentives to encourage early purchases.

Steam pre-orders were unlocked as more people put down money, resulting in a free copy of series opener 'BioShock,' last year's acclaimed 'XCOM: Enemy Unknown' and digital items for the Steam Network's 'Team Fortress 2' game.

Similarly, GameStop's Impulsedriven service offered 'BioShock' and 'XCOM: Enemy Unknown,' alongside an in-game item, while GamersGate clients net $18 off future purchases.
