Sumo Digital, specifically the Sheffield location, is currently hiring for two unannounced projects. Going over the several available job listings some details can be gathered about both projects. One being a open-world AAA action title and the other a 3rd person MP shooter.
Project #1: "We are looking for a passionate Senior Game Designer to work on the next game in an established AAA open-world action franchise." Further described as "a well established IP" applicants are to help "grow the universe of a multi-title franchise". Help is needed to enhance "the gameplay and narrative of an existing IP". A Sound Designer ad describes it as "a huge but unannounced AAA console title with a clear vision of how to make our title truly stand out from the competition." This seems like a contract based project.
Project #2: "We have an extraordinary opportunity for an experienced Lighting Artist to join an experienced team currently working on an unannounced 3rd person multiplayer action title." Further descibed as an "exciting new multiplayer high-profile shooter IP franchise". They are looking for a "game designer specialising in the character, combat, and traversal mechanics to play a pivotal role in developing the core experience of a AAA game from the ground up." Another listing looks for somebody that has "a passionate love of gaming and a strong understanding of modern gaming trends; particularly in the PvP shooter genre." Sumo Digital is mostly known for developing games for major publishers like Crackdown 3 and Forza Horizon 2 (X360 version) for Microsoft, Team Sonic Racing for SEGA and the recent Sackboy: A Big Adventure for Sony. They also develop and publish their own titles like Snake Pass.
