Tanky shotgun front liner. Use 830 or AA12, but any shotgun works really. Packs a little mobility, a lot of reload, but not much additional damage. This is by design. If the first pellet kills the zombie you're shooting at, you won't get temp health. You should be spamming modest spread shotgun rounds into crowds, getting penetration (causing 1,2,3 hits per shot) and triggering bruiser
