New to GURPS: Zombie Apocalypse

On the zombie-stat front, I would recommend going with Injury Tolerence (Unliving) and (no blood, no vitals) and add a Vulnerability to headshots, or just negate the Injury Tolerence when hit in the head or skull. The primary effect is that it reduces the damage from bullets but not most melee weapons (and even though shotguns have the damage of individual pellets reduced by 1/5, hitting with lots of pellets still does a fair amount of damage compared to a handgun). This means you can put a zombie down with gunfire, but it takes more shots than a living person... unless you shoot them in the head. On the other hand, if it gets to melee attack range, your PCs having to use a fire axe or baseball bat won't be at such a disadvantage.

Personally, I'd go with a zombie type that is easy to destroy or evade when by itself (if you're careful) and make the horror come from the large scale of the problem. That also contrasts them with living adversaries who would be more dangerous one-on-one but easier to kill with firearms.
