For the last level: (1) Shut down one Mitochondria to prevent Glucose usage; (2) Find a lot of Glucose to build up FA; (3) Build Defense to prevent some virus from entering (~33%+); (4) Build some Lysosomes (~10); Always remember to keep on finding more Glucose; (5) Save enough FA to mass inflect Poison (~10%+ each time); (6) Always build 50 Splicer; (7) Later on when building mass poison, turn both Mitochondria on to get as much energy as possible. That is all. Good luck!
