Neil Armstrong Achievement
Travel 1000 Kilometers
This achievement is very straightforward but will require a decent amount of time to unlock. The achievement requires you to travel 1000 kilometers on land. Whether it’s a glitch or something the developers intended, the game doesn’t track distance traveled by swimming.
While exploring you might find the blueprint for the Minibike, which will help you immensely when traveling around the map, since even the slowest bike is still a good bit faster than the player can run. Also with the bike you don’t have to worry about riding at night since you can simply outrun any zombies that comes after you. It is worth noting, however, that running into zombies with the bike will damage it. This achievement is cumulative, so you don’t have to worry about trying to do all of it on one character. After you have traveled 1000KM, the achievement will unlock.
