The Ultimate Game Sale for Microsoft's Xbox gaming consoles is ready to launch later this week. However, a leaked test page for the sale has already spoiled the biggest offerings of the sale, with several popular titles included in the list.

A user on the NeoGAF video game forums captured a screenshot of the test page, which revealed deals for Xbox One titles such as Destiny, Halo: The Master Chief Collection, Killer Instinct, Call of Duty: Advanced Warfare, Middle Earth: Shadow of Mordor, The Crew, Alien: Isolation, and many more.

Xbox One owners can avail of savings worth up to 85 percent for members of the Xbox Gold program through the Xbox Store online.

Destiny will be sold with a 33 percent discount for all gamers, while Halo: The Master Chief Collection will be sold with a 25 percent discount, but at 60 percent for Xbox Gold members. Gamers can purchase Killer Instinct Complete Collection with a 33 percent discount, which is bumped up to 40 percent for Xbox Gold members, and Call of Duty: Advanced Warfare can be purchased at 33 percent off for both Gold and non-Gold users.

The leaked page did not list the final prices of the titles included in the Ultimate Game Sale, and all the details contained within it have not yet been confirmed by Microsoft.

The Ultimate Game Sale includes titles for both the Xbox One and its predecessor, the Xbox 360. The sale is slated to launch on Feb. 18 and last until Feb. 24. Larry Hryb, also known as Major Nelson, teased about the upcoming sale last Feb. 15 through a picture posted on his Twitter account.
