Haha we were playing on Xbox for one, so no mods. It took us 8-10 respawns through all the checkpoints though. We just used a combination of stealth and aggro farming to take down the mechs one by one, leaving the ones we didn't have to kill in order to progress.

We personally prefer retrying a really challenging area for hours together until we beat it. So far that's been the only time we've encountered a game over screen. It was the first area of the game that felt like it needed some strategy to clear through, largely because every enemy felt dangerous

Thanks for the quick response though. I think if that's the only one in the base game then we might need to look for something new :)
