Sigma continues blowing away chunks of the infected. He used his grappling cord to pull bots back to safety. "Sir, assault helicopters are inbound. Hold for 3 more minutes." Zack, his AI, told him. Sigma could hear the helicopters. He held out, but kept having to fall back. Once the helicopters lined up at the end of the avenue, Sigma de-materialized Gavin.

Sigma then launches up to help cover the escape of uninflected personnel.
