MASS EFFECT - Priority Hagalaz is a co-operative, story-driven game for 1-4 players designed by Eric W Lang and Calvin Wong Tze Loon 黃子倫. A branching, narrative campaign allows for multiple playthroughs with a different experience every time. The story changes in response to your actions - your early choices influence later missions. Gather Shepard’s squad from a selection of teammates from the Mass Effect trilogy: Liara, Tali, Wrex, and Garrus. Customise and upgrade your squad through experience and optional loyalty missions.
