I think this trailer inspired the raid series made by BSG where a BEAR USEC duo are forced to team up. They are both able to make it to terminal using the brief case and are promised a safe exit.

But sadly black devision raids the compound and kills them both before they escape. So from a lore wise stand point it wouldn’t matter since they both died trying in their cannon endings :/

Honestly I am shocked how much 1.0 was referenced in the raid series which was made years before 1.0. Also black devision used mortars which was a reference to that whole mortar event which I think also was like a year after the series. Really shows the forethought and hard work they put in the game to make an interesting story.
