Other sources

Engineering Foundry Supply Crate

Unlock Engineering Foundry Supply Crate to take what is inside. Several separate draws decide the contents, so you can get more than one of the same item.

Availability and notes

Own a sealed, loot-filled Engineering Foundry Supply Crate. A plain empty container is not this loot source.
Unlock with Disposable Keycard (Command) or Disposable Keycard (Engineering).
Loot is rolled when the crate is created, using recorded luck. On unlocking an unscanned crate, higher current luck replaces its contents with one new fill; scanning prevents this replacement.

Cost

A successful unlock consumes 1 key: either Disposable Keycard (Command) or Disposable Keycard (Engineering).
A rolled item is kept only if it fits inside the crate. The listed chances describe generation, before this space check.
