An Alpha Crawler walks on top of a rock and roars. After this, it travels, down, joined by more Promethean Crawlers as it does so. On the other side of the canyon, Fireteam Majestic is seen fighting the Crawlers. While trading fire, DeMarco gets up and fires his battle rifle. He barely misses one Crawler before a second shot gets it. As the firefight continues, the camera pans toward Madsen and Grant, with Madsen sniping.
Another Crawler is taken out. Grant crouches behind cover and reloads her DMR.
Camera cuts back to Madsen, who snipes another Crawler. After doing so, he stands up.
The Knight fires its scattershot, hitting Madsen in the left of his chest. As Madsen collapses while clutching his chest, the rest of Majestic fires upon the Knight, which has been joined by four more. Hoya then suddenly yells out and dashes out.
