Play a heterotrophic cell, and as your first evolution, evolve a membrane that prevents engulfing. Then, evolve to become a predator.
I could not beat this challenge.
My thoughts on it were:
- Toxins aren’t worth it, as they travel way too slow. Use pili instead.
- If you evolve a mucocyst and slime jet, you won’t need flagella.
- You will need to die several times to unlock offensive parts, since you can’t engulf for them.
