Effects of Man by Krotosin reviews
During the shitshow that Eden Prime was, Shepard finds a man buried near the Beacon. With him, two AIs, one from Reach, the other from Typhon. With him at her side, Jane's mission is easier. If it wasn't for the fact he's a hyper-lethal killing machine, with malware stuck in his head. And a bit of an odd case. Mostly Titanfall and Halo, with some (a lot) Deep Rock Galactic.
