-- concept: fire a plague rocket.
-- it explodes in a cloud, cloud applies disease stickers to biters.
-- initial impact fires many plague projectiles in all directions.
-- impact with biter applies sticker and a new set of plague projectiles.
-- each time a projectile is spawned deal small damage in radius to biter bases.
-- sticker slows and deals damage. biters are only damaged by the sticker.
