although that is an excellent idea the call of duty franchise had zombies in WaW. so say... 3-4 years ago? and there they came up with the first 4 zombie maps. so then came modern warfare 2 and the company split/lawsuit bullshizz. it seems very unplausible to think that this will be the end. or that the first 4 maps : nacht der untoten, verrukt, shi no numa, and der riese has anything to do with the 8 steps.
