Nothing Can Go Wrong
From Halopedia, the Halo wiki
Fireteam Crimson exits slipspace at "the Refuge" to assist Infinity Science. Shortly after they arrive, the UNSC contingent is attacked by Prometheans and Dr. Boyd flees to a safe room. Crimson desperately tries to protect the Science Team while they try to figure out a way to prevent the Prometheans from translocating into "the Refuge." After surviving multiple waves of attackers, Crimson is able to identify and destroy the device which allows slipspace portals to open, ending the Promethean threat. Spartan Jared Miller orders Crimson to stay on station while the area is locked down.
