Still, 5GB every 30 days, that sucks.
EDIT: I figured out an explanation for the Hazmat grunts; They're normal military and partialy trained recruits in Hazmats because of the Hazardus areas/Xen aliens (who knows, maybe the gov't thought they were radioactive)
Anyway, since they're normal military, they only get cheaper hazmat suits, as opposed to the (now mostly dead) HECU, who have expensive PCV units.
EDIT: D'you think you guys could supply me with a zombie model with a different head that the one you're using now? The one you're using now makes the game crash whenever it's shown. I'd use Barney, Slick, and Grunt(?) heads, but they'd all be generic faces, and I'd prefer to use a face that could be anyone.
