They sell a “battle pass”, runs about 6 weeks, and with that purchase, you open up certain awards and prizes (skins, “cooler looking” tools) as you move up in the experience level. So they sell those every 6 weeks, on top of the aesthetic upgrades, like “skins”, cooler looking harvesting tools and visual upgrades. But you can’t buy yourself into being better/faster/stronger than the next player. So no buying better weapons. I love that. Even playing field for all. But skins can cost up to $10-15 USD.
