[PC~Steam][2016-2021 (maybe)] Game where a group of characters explore and battle AI/Robots in 3/4 isometric in turn based combat

Platform(s): PC Genre: RPG/Strat(maybe)

Estimated year of release: I know it was after 2016 andam sure it was before 2021 I last played, I think

Graphics/art style: Top down 3/4 isometric, I cannot remember if 3d or if can rotate map. Was not pixel art I am sure. May or may not have some sprite based assets

Notable characters: No real notable character I remember, except sort of one character who was an engineer and had experience with the robots or whatever they were called in one of the missions they discussed it prior...i think

Notable gameplay mechanics: turn based combat, utilization of some elements of the location, like switches and wepaons maybe that were mounted on the gameplay area? like turrents or something you could activate, it is really fuzzy...

Other details: I termember an entrance to this one mission area, walking on a wall, sandstone colored brick wall, you could cross a narrow bridge or go around to a platform entrance, felt like a large fortress' wall. Once inside there were like factory elements or research lab elements of some sort, there were some mobil robot mobs, but also iunside some larger stationary I think. I have such a strong memory of the wall aread, but it's all I really can remember, and that one guy was an engineer and could do something with that skill to the ai/robot enemies. I have been looking for the title of this for a while now cos but even looking through my some 2000 games on steam, I can't find it...

what I do remember about the wall area outside in that one mission is that the wall was at a SW/NE angle, and it came to a platform that opened to about 3x the width with one or two dark entrances at that one spot that entered the factory and as you moved, there was a surprise attack of a number of those whatever the enemies were...

I can see the image of that so clearly but... no luck. Help
