Hades asked what Keaton was already thinking. If the two went into the room at the end of the tunnel and into a firefight, they could be flanked from behind. "We search the rooms, regardless of the contents," he said, thinking a quick plan. "If patrols are in there, then we need not worry about them in the final room. However, if they are storage, then we can close them off and barricade the openings so no one gets through, if there is a way around." Keaton continued thinking; if there were enemies in both rooms, then as soon as one door was opened, the others across the path would be alerted. Either both rooms' hypothetical patrols are drawn out into the open to be shot there, or Keaton and Hades clear one room quick enough to use it as cover against the enemies in the room opposite the hall.
"Assume both rooms have hostiles inside and draw them out into this hallway. I hypothesize you can't be killed by normal humans, so I'll be down the aisle prepared to shoot." He paused, considering Hades's ability from before, killing the incapacitated guards. "Unless you can kill everyone without a sound, that may be a safe plan."
