Platform(s): PC and I don't know if anymore (maybe ps4?)

Genre: Looter-shooter diablo style

Estimated year of release: 2010-2020, most likely closer to 2020

Graphics/art style: Sci-Fi top down or isometric shooter, diablo-like graphics but more greyish/metallic, with a bit of neon. Ascent (new game) reminded me of it.

Notable characters: There were like 3-4 robots, because the game was focused on co-op and each robot had a class/weapons. They were color-coded like orange for assault, blue for support, green for medic, etc (colors don't match the classes, just an example)

Notable gameplay mechanics: Shooter looter, like diablo but with guns. Robots could upgrade their skills and had a variety of weapons.

Other details: I think I saw a video review of it on 2019-2020 but it could be older and I just found the review that date.

Thanks in advance
