The fall of meteorites brings "distortion factors", and creatures evolve wildly. Plants eat meat, animals become giant, and humans awaken supernatural powers but may also lose control and become monsters. Hot weapons are ineffective (abnormal creatures will evolve resistance), and cold weapons + superpowers are the mainstream.
Protagonist Goldfinger: Infinite Synthesis Station
Any two (or more) items can be combined to produce new items
The synthesis formula is not fixed, but there is "compatibility" - the synthesis success rate/quality of related items is higher
Dismantling items can obtain "material points", which can be used to maintain the base or strengthen them.
Synthesis has a "critical hit" mechanism - a very small probability of producing super-standard items
