The publisher is offering free copies of AC IV: Black Flag and AC III to those who buy Elder Scrolls Online through uPlay.
Consumers who pre-order the Bethesda MMO from Ubisoft’s digital store will also receive a free copy of the latest Assassin’s Creed.
Launching as both physical and digital editions, the latter offers players the Explorer and Imperial DLC packs, in addition to five-day early access to the game.
But to sweeten the deal, Ubisoft is offering those who pre-order the £69.99 Imperial Edition a free downloadable copy of Assassin’s Creed IV: Black Flag.
Meanwhile, gamers who offer for the standard edition of the game will receive the Explorer DLC content, three days early access and a digital copy of Assassin’s Creed III.
Elder Scrolls Online launches across PC and Mac on April 4th with Xbox One and PS4 editions to follow in June.
