Big franchises like Call of Duty and Battlefield are jumping on the battle royale bandwagon this year, but another big time series, Assassin's Creed, isn't taking a stab at it just yet. Game director Scott Phillips was asked by Game Informer if there have been any meetings about putting a battle royale mode in Odyssey, and he responded by saying no, there haven't been.

That's all he had to say on the subject (this was part of Game Informer's rapid-fire interview video series), but Phillips did go on to say that Odyssey won't have multiplayer at all. Head-to-head multiplayer was introduced to Assassin's Creed with 2010's Assassin's Creed: Brotherhood, but later games in the series moved away from this. For Odyssey, Phillips said he wanted the development team united to make the best possible game (he also said in the interview that a total of eight studios are working on Odyssey).
