SteamWorld Heist II

I can confirm that if you have a robot get blown-up, you can go into the menus and select “Restart Checkpoint” and you will still get this achievement at the end. The robot only counts as dead if the crew member is dead at the completion of the mission.

I had dozens of robots get blown up throughout my playthrough but I always reloaded the checkpoint as soon as I could except for one time. I was awarded this achievement upon completing the game.
