The Generators accumulate different resources over time. The Supply Crate, K-Marks Generator and Aurum Generator deliver a slow but steady stream of In-Game currency and Items. Generators work independent of wether a prospector is logged in or not, but are capped at certain limits. For full efficiency, the Generators must be emptied regularly.
Every 23 hours, a Supply Crate with a random collection of Weapons, Gear and Consumables can be claimed. The items available depend on the Level of your crate, which can be increased with Quarter Upgrades.
The 23h timer to the next one starts at the moment the Crate is claimed.
This Generator produces a set amount of K-Marks every hour, until a limit is reached. The generation speed and the limit can be increased.
Like the K-Mark-Generator, this one produces Aurum at a fixed speed every hour up to a certain accumulation limit. Albeit at a slow rate, this gives access to the "premium" currency to all prospectors.
If a prospector has insured items and died on the surface, the K-Mark payout or the salvaged gear can be claimed here after a certain amount of time, usually less than an hour.
Twitch Drops can be claimed here after linking with Twitch here. Once linked you have to watch a stream for a period of time and then claim the drop on Twitch.
