Quite frankly, co-operative gaming is now so ingrained in the genetics of shooters that it is much rarer for a game not to have it than to have it. The only other major shooters of the last few years that have no co-op are Call of Duty and F.E.A.R. 2, and the latter is a horror game and has the time slow mechanic which would both be incompatible with co-op gaming.Indigo_Dingo said:Who says it should be?
If Killzone 2 had co-op, it's value to me would increase massively, because it would probably convince my regular co-op buddy to pick up a PS3, and I would play it that way, probably to the exclusion of playing it solo, which I have done with every other co-op shooter for the last few years.
