So i finally finish the easter egg on split screen after two days, and we leave the wunderwaffe til the beginning of the next round since i unfortunately died and had to wait to return. however not anticipating the time it took for the drop off to show both of us got took out by zombies on a major scale (rookie mistake, i know) therefor not actually getting the wunderwaffe and crying inside for the time spent doing the easter egg. i did get the two trophies. but my question is for anyone that can answer me is what will this do for the game as i dont seem to have the wunderwaffe when i start the game and i cant find the answers anywhere on the net!!!
