Steam top ten sellers chart: July 22-28

Valve has revealed Steam’s top selling titles for the past week.

ArmA II, imbued by the power of its DayZ mod, simply refuses to relinquish its firm grasp on the top of the charts. The aging FPS came out ahead again this week despite some heavy competition in the arrival of pre-orders for Borderlands 2.

Prototype 2 makes its post-launch debut on the chart, sharing the final spot on the list with a couple other titles following its release earlier in the week.

The list reflects the impact of the Steam Summer Sale promo’s last few days as well.

1. ArmA II
2. Borderlands 2
3. Left 4 Dead 2
4. The Elder Scrolls V: Skyrim
5. Orcs Must Die! 2
6. Borderlands Game of the Year Edition
7. Civilization V: Gods & Kings
8. BioShock Collection
9. Fallout New Vegas Ultimate Edition
10. Batman: Arkham City and Max Payne 3 and Prototype 2
