Dead Rising 3 will feature 2 player co-op but at one point it actually featured four here's what Mike Jones said@

“We played around with different ideas. The main challenge that we set out on was the scale of the world, making this massive world with more density than ever before, more weapons than ever before, more stuff than ever before, and getting all that working on the Xbox One with a visual fidelity upgrade. And then being able to network all that reliably with no tethering – that was a huge accomplishment for us, right?

“Obviously we’d like to have three players, four players, more players, and we did some rough tests, and the networking fidelity started to break down.”

Would you like more than 2 player co-op and feel that this is a bummer or do you believe that 2 player co-op is more than enough?
