I got all the way to the boos stage till I finally died for the first time. When I clicked "retry" it started my game from the checkpoint but no arrows are showing up.. I don't want to start all over again T_T
And because of the recession the employee's of Papa's chains have still not found suitable well paying jobs. Working long hours on a very short staff. I blame big name corporations like "Wally World"
@ klimtom thanks for the hints ;D I found it more efficient to use "barrels" instead of the "fake wall". I usually run from one end of the map to the other. Equip the barrels and run up vertically while pushing the space button. Once the barrels are in place I hide behind this new "wall" and once the zombies walk up o it I shoot with the grenade launcher keeping a safe distance :3
It's the number in the bottom right corner of the title screen. :D
