It is difficult to escape zombies in the standalone game, compared to the DayZ mod for Arma II. When attempting to utilize terrain, hills slow you down while the zombie still moves full speed. Using barriers such as fences will slow the zombie down 50% of the time, while the rest of the time they are able to clip through it. Not enough bandages spawn for the amount of bleeding involved. With zombies this tough, it is difficult to try other parts of the game and report bugs as we come across them.
