You can get this achievement by simply letting all of your allies lose a total of 5 matches.
I recommend using only the Guard move for the whole match since it doesn't damage the enemy and it doesn't make you fully immune to attacks.
After a short while (2-5 mins max) all your allies should die and the game will inform you that you have lost.
Once you click Ok, you will spawn in a bar. Exit the bar and head to the circle with a rocket symbol and look for another enemy.
Rinse and repeat for 4 more rounds and this achievement should unlock.
You can also get an achievement for losing once:Solution for Quantum Hopper in Star Renegades (Win 10)Couldn't find a video so for now, that's all I got.
