Enact a new rule, “Conflict”:-

Each Infected has a number of Attacks, defaulting to one. If an Infected has both a greater Size and more Attacks than a specific Infected (the “Beta”) who they share a Chamber with, they may reduce any one of the Beta’s Phenotypes by 1 and change the Beta to be Roaming.

Create a new subrule to “Hold Items” entitled “Claw”:

Item Name: Claw
Bulk: 0
Grip: 1
Method for acquiring: An Infected may increase their Mutation by 1 to gain a Claw.
Effect: Each Claw provides +1 Attack. Claws are Bodily Items.

In the rule “Hold Items”, replace “can discard an Item at any time” with “can discard a non-Bodily Item at any time”, and replace “may randomly select an Item held by that Infected” with “may randomly select a non-Bodily Item held by that Infected”.

In the rule “Crash Site”, after “set to zero, 4, 4 and 4 respectively” add “and they lose all Bodily Items they are Holding”.
