As before a large red spiral signifies the opening of another portal.
After several seconds everyone piles through the portal with(almost literal) buckets of loot, some of them a bit bloodier than others, but everyone in decent shape.
Once everyone was through the portal began to spiral closed, only to stop at a pinpoint, re-open, and for a man in green armor to learn through, drop a large gun on the floor, and give a quick salute before the portal closed again.
When inspected one would find the words "BFG 2704" written on it.
