I've been hopelessly addicted to this game for a year now. So I opened a community about it: https://lemmy.dbzer0.com/c/mechabellum

I've played this in the past because of the unique co-op feature. You can team up with another player and play the game. You both do a battle and if you win, your units can go over to the other fight to help your buddy out. It's super fun and I played it a good number of hours with my brother. The biggest issue however was the camera, you can't hardly zoom out. That means in co-op you can only see your own battle, you can go look at your buddy's battle, but that means you can't see your own battle. This sucked really bad, because you couldn't see what worked and what didn't and how it was going overall. For us this kinda ruined the co-op game mode, it was just like playing the game solo and sometimes you would get help randomly. We submitted it as feedback to the devs, saying in co-op you need to be able to see both battles at the same time, but I don't think they ever did anything about it. So we've stopped playing it, maybe we'll give it another go sometimes.

Wonder if it is at all reasonable for the steam deck. I presume no controller scheme.
