While The Last Stand: Aftermath has lots of different resources to collect, there’s one thing that’s more important than anything else: stamina. As well as determining how much you can hit zombies, it’s also vital to have as much stamina as possible for when you have to hot-tail it to your car at the end of a level.
Luckily, you can also increase your max stamina in The Last Stand: Aftermath across different runs, meaning that new survivors after death will also have their max stamina increased.
To increase max stamina in The Last Stand: Aftermath, you need to find your way towards a upgrade radio, which randomly appear across maps. Use your focus and see if the icon pops up; they don’t seem to spawn in every single map. You will need a battery to power on the radio; these also spawn randomly.

Interact with the radio once powered on and you’ll be able to spend your Knowledge on various upgrades. Knowledge is earned from collecting research-like items around maps and, like most things, can spawn randomly. We tend to find a lot in cars, though.
Then, find Body Upgrades and select the pair of lungs to upgrade your max stamina by 10%. You can dump more Knowledge points into stamina to keep on increasing it, up to level 4. It’s well worth doing, even if it might take a while.
The Last Stand: Aftermath is available on PC, PS4, PS5, Xbox One, and Xbox Series X | S.
