Armored Core: For Answer

Omer Science Technology is a West Asian military company with superior political power and high standing within both the League and Collared. They would play a significant role through the entirety of the Armored Core 4 sequence.


Like Akva Vit, they are one of two companies to find success developing Kojima Technology independently. At the time of the National Dismantlement War, they were considered to be a subsidiary of Rosenthal. They had a deep rivalry with Akva Vit, since the two companies were considered leaders in the Kojima tech field.

Armored Core 4Edit

Omer decided to align with GA during the Lynx War, as this provided them with the perfect opportunity to engage in open warfare with the Rayleonard group, their Kojima rivals. Omer's executives were also able to obtain Rosenthal's support, after which they became much more powerful within the Rosenthal group.

Unfortunately, as luck would have it, Omer was quickly forced onto the sidelines due to suffering heavy losses. Although they avoided direct engagement from then on, they relied on the assistance of a rising LYNX by the name of Joshua O'Brian to fight for them.

Omer's LINX Mido Auriel took part in the Battle of the Abandoned City, alongside Rosenthal's Leonhardt, and The Anatolia's Mercenary, working under contract to GA at this time. The three of them together were able to take out #01 Berlioz and his elite NEXT Squadron.

Shortly afterward, Omer forced Joshua O'Brian to attack Anatolia (presumably under threat of Aspina's destruction), piloting a Prototype NEXT named the 00-ARETHA in a battle against Anatolia's Mercenary, his friend. Although Joshua appears to have damaged Anatolia, the Anatolia's Mercenary's intervention was enough to save the colony, and Joshua died when the ARETHA's core exploded after being defeated.

Armored Core: For AnswerEdit

Omer gained a firm technological advantage when they took in a number of engineers from Rayleonard after it fell in the Lynx War. They are in competition with TORUS over Kojima Technology, due to TORUS containing elements of Akva Vit (and whatever Rayleonard engineers in Akvavit's service at the time of its collapse) in its infrastructure.

By the time of Armored Core: For Answer, Omer has seized power within the League of Ruling Companies, although it has failed to achieve complete hegemony due to the independent streak of such groups as GA and TORUS. It is now more powerful than Rosenthal.
