Microsoft has launched an Xbox Backward Compatibility Super Sale, providing up to 75 percent off the pricing of Xbox 360 games that will also work on Xbox One.

The firm is offering over 275 Xbox 360 games for sale during the promotion, which runs from today, May 16, through May 22.

You can find the main page for the sale here, on Xbox.com. But if that’s not coming up for you—it’s not working for me as I write this—Major Nelson also has a full list of sale games.

Some key games on sale include:

• Alan Wake’s American Nightmare (75 percent off)
• Army of Two (67%)
• Assassin’s Creed (75%)
• Assassin’s Creed II (67%)
• Assassin’s Creed Revelations (67%)
• Assassin’s Creed Rogue (67%)

And that’s just the A’s. Bioshock, Bioshock 2, Bioshock Infinite, Bioshock Infinite Season Pass, Borderlands, Borderlands 2, Borderlands 2 Season Pass, Braid, Call of Duty 2, Call of Duty 3, Call of Duty: Black Ops, Call of Duty: Black Ops II, Call of Duty: Black Ops II Season Pass, Call of Duty: World at War, and many, many more games are also on sale. It’s an impressive list.
