Assassin's Creed IV: Black Flag

On Ubisoft Connect, from £25.94 at CJS CD Keys (Gold Edition, key, no checkout fees); on Xbox, from £14.50 with the £2.55 fee its feed gives at Kinguin (key, plus fees at checkout); on Steam, from £28.10 at CJS CD Keys (key, no checkout fees). Prices checked 14 November 2026.

Not now at the official stores I check: only key shops have it in stock, and each row says which region its key is for.

The prices I lead with are only from offers their shop says work on a UK account. Ubisoft says some keys only work in some regions, and that a key bought from an unapproved seller can be banned; the shop handles a refund or a swap. Xbox says a code has to match your Microsoft account's country or region, and that using a VPN to get round it can get a purchase reversed or the account restricted. Steam leaves region limits to each game's publisher. If a key won't activate, the shop you bought it from handles it: Steam doesn't refund keys bought elsewhere.

Ubisoft Connect keys are activated in the Ubisoft Connect app, and the game stays on your Ubisoft account. Xbox codes are redeemed on your console or at xbox.com/redeem, and the game stays on your Microsoft account. A Steam key goes into the Steam app (Games, then Activate a Product on Steam) or Steam's website, and the game stays in your library.
