Steam offers downloads of Mark of the Ninja for Windows, Mac, and Linux for $2.99. That's a buck under our mention from a year ago, $12 off list, and the lowest price we could find.

Also available are downloads of Mark of the Ninja: Special Edition for Windows, Mac, and Linux for $3.59. That's a low by $14. (If you already own the standard edition, you can get the Special Edition upgrade DLC for 99 cents.) Deals end August 19.
