[Skull] Famine Skull: Trust Us, Bring A Magazine [Submitter] NThro_Sraom [Updated] 10.13.07 [Level] The Ark [Summary] 
This skull is found on The Ark. The effect of this skull is it makes weapons that enemies drop, have half ammo. So for instance, say you pick up a beam rifle that you got from killing a jackal. It usually has close to 88 charge right? Well now if you're lucky it'll have 41 charge. Makes the search for weapons longer however it gives you a 2x multiplier on campaign scoring. Anyways, onto finding the skull.
