While Jack and Valerie are still unconscious

Kriegel abducts them.
Jack wakes up to find himself in a helicopter with Kriegel and Valerie. Jack is thrown off the helicopter by an elite guard and Kriegel sarcastically says, "Survival of the fittest, good luck with that!" On the ground, Jack finds a tossed rifle with only 10 rounds of ammunition. He needs to rescue Valerie a third time, and his needs to cross the security perimeter like Trigens did. Upon reaching a mercenary weapons depot, Jack finds his arm turning green, and Doyle states that the antidote should be able to deal with it, but the explosion may have filled the air with mutagenic substances that the serum developed by Dr. Kriegel should have a way to deal with. Jack decides to go straight to Kriegel for treatment.
