Engineers Information

Engineers can apply unique bonuses by staffing them in the Proving Ground as well as other Avenger facilities like the Psi Lab. Engineers are gained as recruits from completing Missions. Every facility with the exception of Laboratory, Guerrilla Tactics School and Shadow Chamber can benefit from staffing an Engineer.


A Gremlin is a robot that you may staff in a Workshop that behaves like an engineer except that it affects all facilities adjacent to the Workshop. As such a single Gremlin optimize your Avenger by placing Workshops in the middle of the Avenger and surrounding the Workshop with facilities that benefit from staffing an Engineer/Gremlin. Staffing an engineer in the Workshop will gain you access to 2 Gremlins.
