I've been a little tied up with other projects recently and intend to knuckle down to the rules over the next few months.
As it stands:
The Core Rules including Turn Sequence ,Movement and combat are completed. Zombie Deployment, movement, combat and spawning is completed.
I'm still working on Vehicle rules, Character generation and equipment/pick-up lists.
So far I've done about 45 pages which doesn't include pictures, fluff or examples.
As soon as I've got something I think is usable I'll post some Beta rules to play around with.
Regards
PM
