Ubisoft have outlined plans to support both the Nintendo Network together with their in-house Uplay service.
The Wii U's online system is designed to incorporate third parties, and Ubisoft president Yves Guillemot hopes that the company and Nintendo can work together. Uplay is used for multiplayer, achievements and digital distribution - networking fellow Ubisoft players regardless of hardware.
Guillemot also confirmed that plans are in place for Ubisoft to offer retail games on the Nintendo eShop once the option becomes available - including launch titles ZombiU and Assassin's Creed 3.
The publisher may also offer up download codes to retailers as "when people go to the shop they want to get information on what game to buy and also how to play it and so on".
