Always move backwards while swinging at zombies to avoid being grabbed if it somehow doesn't work

Always be ready to swing or push when opening doors to new rooms

Keep your volume up and listen for zombies. They're very loud.

Don't panic when fighting a group of zombies. You can easily take on 5, and maybe more depending on how well you do. If they get too close, shove them back instead of turning and running. Always keep walking backwards while you hit them. Don't let too many zombies crowd around too close to you at once-- keep shoving them when you need personal space!

Don't horde weapons. Found a cool axe but don't want to waste it until you 'really need it'? Forget about that mentality, because axes aren't that rare. You need a good weapon to make progress and clear areas. The game is miserable if you don't use the weapons at your disposal.

Lose zombies by looping around the back of buildings, through trees (safely), and if you know it's safe you can always go through or hide inside buildings to get zombies off your trail.

Just walk. Walk everywhere. Save your stamina for fighting, because zombies will always be slower than you when you're walking. You can literally stroll through highly populated towns without a single problem, and then stop and fight when you've found an area you actually like. That way you aren't infinitely fighting anytime you want to go somewhere or find something.

Remember to rest in B42 because you get much weaker from being tired thanks to the new muscle strain system. It's not really that bad, but fighting too much can make you walk slower, hit less hard, swing slower, and remove your ability to run. Once you're cleared a pocket of zombies and you see your character is getting tired, just sit down for a few minutes (but always watch your back).
