We have already been like that for a while now . <| sep |> Mudsdale is good , Mudbray gets an almost earthquake at level 24 9595 instead of 100100 <| sep |> Speed will change based on terrain using certain types of locomotion . If you ' re on foot , normally it won ' t make a difference because the zombies and bandits chasing you are also on foot , so even if you did get a speed bonus or penalty , the mobs chasing you would get the exact same one , and neither of you would pull ahead . Differences are minor if the exist . On foot the most noteworthy things are furniture , fences , and other obstacles which have a much larger cost than normal terrain unless you have the Parkour Expert talent . Spider webs can also trap you , but they ' re pretty rare and easy to spot . And rubble will not only slow you down , but you have a chance at falling down and slicing yourself on twisted metal wreckage which , for someone without medical supplies , can mean a pretty early death . Terrain is a much bigger issue if you like to wheel about on things like rollerblades . You effectively get double the speed on hard surfaces , but half the speed on dirt and rough terrain , so terrain becomes absolutely critical . It also affects vehicle speeds , depending on the wheels .
