Microsoft's Xbox Ultimate Game Sale goes live tomorrow, but the discounted prices are already available via the Xbox Games Store.
Borderlands: The Handsome Collection is 40 per cent off, as is Halo: The Master Chief Collection and Telltale's Game of Thrones season pass.
Download versions of Dragon Age: Inquisition, Geometry Wars 3, Shadow of Mordor, Sniper Elite 3, Slender, Sleeping Dogs and Watch Dogs are all half price.
Even higher discounts go to Far Cry 4, Killer Instinct Complete Edition, Saints Row 4, Terraria and Titanfall - all are 60 per cent off.
Meanwhile, Microsoft's excellent Ori and the Blind Forest is £12, down 25 per cent from £16.
The biggest saving at the moment is Lego Batman 3's Deluxe Edition, which includes all of that game's Season Pass content. Normally priced at £57.49, you can pick up the whole thing for a very reasonable £14.37.
