Grand Theft Auto V held tight to the top spot on Steam's weekly best selling products chart, but Killing Floor 2 arguably had a better showing with two of its products finishing in the top three.
Killing Floor 2 took the runner-up spot, while the game's Digital Deluxe Edition finished right behind in third. Counter-Strike: Global Offensive and Skyrim's Legendary Edition round out the top five.
On the opposite side of the list, we see some titles in danger of slipping off the top ten, including Cities: Skylines in eighth, Elite: Dangerous in ninth and Mortal Kombat X in tenth.
Here's the full list:

  1. Grand Theft Auto V
  2. Killing Floor 2
  3. Killing Floor 2 Digital Deluxe Edition
  4. Counter-Strike: Global Offensive

  6. Middle-earth: Shadow of Mordor Premium Edition
