If I had to guess- The Knight (Shovel Knight), The Traveler (Hat Kid), The Genie (Uhh...I'm gonna guess the Genie from Aladdin. Not sure who else this could be. Shantae), The Soldier (Nathan). Then the new ones...The Warrior (I'm actually stumped. I have no clue who this is. The Knight? X?) the Dragon (Nylocke...?) The Light (Niko from OneShot?) The Prince (Uh...Ralsei...? I'm stumped again.) Mostly guesses here, nothing I can see in a pattern.
Also, I posted this to someone in a conversation...but it's essential info basically.
The building (Being robbed) is four floors tall, with a basement level. The group, I'd say, are on the top floor. There were a handful of the robbers searching the upper halls and offices searching for physical things to steal. The third and second floors are office spaces, the first floor is a lobby, and then the basement is where they are stealing data from the servers. Most of the robbers are likely on lower floors, so as they proceed down the floors, they could easily encounter and incapacitate the robbers- who weren't a big team to begin with, only about 16 of them. Well, twelve now...
I'm not sure if Sam would kill Snake. I mean, maybe spurn of the moment, but Snake basically saved the world thrice at this point. Well, at his point. That being said, Sam probably isn't one to be staying in the loop of who saves who. I dunno, but if he kills Snake he is definitely going to die at some point because Raiden isn't about to play around with him. He had reason enough to want him dead before, but he's going to tear Samuel from limb to limb in that case.
