Mass Effect - Rebirth
Eclipse is a mercenary corporation that was founded by asari commando Jona Sederis. The organization provides effective security and firepower for prospective employers; they have few scruples about the nature of those who hire them, so long as they can afford their services. Eclipse mercenaries work in teams of troopers and vanguards which may be led by more experienced commando units.
Eclipse in general favors stealth, discrimination, and “intelligent” ways of conducting battles. They are not as disciplined as their more established rivals in the Blue Suns, but make up for this with cutting edge equipment and weaponry, as well as their extensive use of biotics. Eclipse also has many ventures that delve into smuggling; they once controlled nearly 20% of all smuggling on Omega, although that has dramatically changed in recent months due to the Cerberus conquest of Omega, the subsequent fight to reclaim it, and the fact that the bulk of the survivors went on to fight the Reapers and were therefore gone when the relay went down.
Those Eclipse still in the Omega nebula still specialize in transporting illicit goods and criminals from place to place.
