Echo of Ada is a third-person shooter developed by Game Studio. It is part of a multimedia franchise that includes the anime Synduality: Noir.
The concept of the series revolves around relationships between human and advanced AI humanoids. As a Drifter, you’re assigned an AI partner called Magus and can customize their appearance.
The video shows the four base appearances (two male-looking and two female-looking). You can pick their specialization in combat and various appearance aspects, picking colors and using sliders.
At the end of the video, we can also see the mech (Cradle). You can pick the parts for arms, legs, body and these will impact their stats. Cradles may equip up to two weapons.
