Unlike that other well-known series that you surviving nuclear (ahem) fallout in a drab, gray-and-green world, Krater's developers at Fatshark instead give you a very lush world to explore. Towns are filled with neon lights and scavenged metal patchworked into buildings, while the world outside their walls teems with life and color, albeit of the mutated, trying-to-eat-the-gas-mask-off-your-face kind. There's also a lot of world outside the walls to explore: travel takes place on a huge world map dotted with settlements and zones surrounding the crater in the center.
Krater's Freediggers are equipped in the same way its towns are built, with a combination of new tech and patchwork scavenged goods. Tanks carry rebar clubs wrapped around a concrete head, while ranged attackers snatch up scavenged or tinkered rifles and pistols to keep the mutant hordes at bay. The art style isn't quite as cartoonish as Team Fortress 2, but has a similarly-skewed sense of proportion to it: tanks are big and hulking, while healers are small and slightly dumpy-looking. Gas masks also cover everyone's faces, making every character look just a little disturbed and alien.
