Revision as of 04:20, 7 February 2018

Engineers can be used to improve various components of your ships.

Each engineer must first be discovered through either common knowledge or via another engineer, and then unlocked by completing their requests.

List of Engineers

Below is a table showing all 20 engineers, how they can be discovered and unlocked, and what blueprints they have.

Blueprints shown in bold are the highest tier of that blueprint available. For Life Support this is G4, for all others this is G5.

Blueprints shown in bold and italics can only be obtained from one engineer, making them mandatory if you want to use that blueprint.

Whilst both Elvira Martuuk and Felicity Farseer lack a mandatory blueprint, they are the only two engineers offering the same G5 blueprint. This makes either one of them mandatory.

Marco Qwent is one of two unimportant engineers, only needed as a stepping stone to get other engineers.

Colonel Bris Dekker is the only engineer that doesn't need to be unlocked, as they offer no mandatory blueprints and no engineer is locked behind them.
