My second playthrough I used just one hamster to doom the world. He is now the loneliest hamster because he's the strongest. There's a single hamster with heat vision, who stands alone as the peak of his species, and can no longer relate to any other gerbil.
He's a victim of his own success. I named him Conquest. (I did have to add more hamsters to end, but it started with him. My strongest soldier.)
I enjoyed playing this a lot!!! :D
