hey guys, new to this forum but i noticed you are looking for an easter egg step, me and my friends were playing last night and when in the belly of the worm there is stomach acid. i thought maybe if you kill zombies in the acid you are feeding the worm? we kept going down because there was that many zombies, ill give it a go today on my own to see if i can get further but i noticed when you kill the zombies inside the acid you are feeding the worm? what happens when this is complete has anyone managed this step? let me know thanks or add me on PSN suttie420. PEACE!
