Statting Cyberzombies is pretty easy: Take a baseline human with 4 in every Attribute:
Give them four cyber limbs with 9 STR and 9 AGI, Reaction Enhancers 3 and Wired Reflexes 3 for a total of 4+6= 10 to REA and 4d6 Ini
Suprathyroid gland for +1 to Body and Adrenaline Pump 3 for +3 to WIL, Pain Editor for +1 to WIL and -1 to INT, INT Enhancement +2
Skill Wires 6 and a generic +3 bonus for various combinations of implanted helpers for a total of 18 dice in combat.
Innate Armor is 18 (Cybertorso+4 limbs+Titanium Bone Lacing)+ regular FBA 18+ 3 Bone Lacing Body + Body 5 = 44 Soak

Ini: 15+4d6
Defense: 15
Full Defense: 23
Soak: 44

Drawback: They need to be online at all times (which is the usual precaution against them going rogue)
