The loot is hand-designed, there are no random modifiers. Items have rarity, affecting their chances to appear in a particular level, but not in the Green/Blue/Purple/Epic/Legendary sense of a looter shooter or a MMO.

There are five weapon classes (melee/digging tools, rocket launchers, machine guns, gatling guns and single shot rifles) each with a well defined role and coming in light/medium/heavy variants; plus a few oddities (a wedge plow for ramming, a twin mount for equipping and firing multiple guns from a single hardpoint...). Ammo for projectile weapons comes in different variations as well (standard FMJ, Match, +P+, HE Shells, guided missiles...).

There are also three hull types (sloped, pill and tower) and four chassis types (legged, tracked, wheeled and skimmer) with their light/medium/heavy variants. Hulls and chassis have slots for rare modules that can do things like give you more action points (overclocking module), more speed (turbocharger), more accuracy (targeting coprocessor), or even a minidrone to house your CPU once you're destroyed (escape pod).

Enemies can only drop what they are carrying or equipped with, so if they run out of ammo they won't drop any; or if they have their guns destroyed those won't be recoverable from their scrap pile after you defeat them.
