I want a shambler mod or something later on, or maybe even added officially, might make things even more diverse.
Cause like right now, the game takes place 2 weeks after first infection, maybe make some missions that take place a couple of weeks later, where the zombies have decayed a bit more and because lack of muscle tissue they cant run as fast but shamble about instead. And because the extra weeks there would be even more infected, strengthening the shambler 'army'.
Mixed up with some recently infected (the fast zombies we have now), and the special zombies, sounds even more interesting
