Not all Electronic Arts-published games will be given the Project $10/ Online Pass treatment. Rather than slap Syndicate with a one-use code that unlocks the game's multiplayer features, EA will keep such access free, to grow interest in the shooter's co-op mode it says.
Syndicate is being published by EA Partners, meaning it doesn't own the studio (Starbreeze). But EA does own the intellectual property behind Syndicate, making this a curious choice. Especially as Kingdoms of Amalur: Reckoning another title being published under EA Partners—with heavy, direct investment from EA—will be subjected to Online Pass treatment, and it has no multiplayer component. Other EA Partners titles—notably Crysis 2—have avoided such restrictions.
