what are these 2 burning?

I just keep invisioning this comedic scene begining when Holloway yell's out "FLAMETHROWER FIGHT!!!" Then after one of them is seriously injured they realise their mistake and attempt to vaporise him in order to hide the evidence.

That´s fucking hilarious!

Haha ... That's someone in a spacesuit ... or something coming out of it ...

Looks like it's from the same scene in the trailer where the mutated guy is tossing another crewmember thru the air, maybe they're giving beardyman a proper toasting?

I think it's the Thing :D

Probably Fifield :(

Maybe but then where are the rest of the crew/mercs in the gun shooting scene they come through that door. Looking at the scenes, i think and i could be wrong that some of the crew are torching something or some objects. Then Fifield Mutant ambushes them to stop what ever they was doing and starts to throw the flammer guys around, and he is then stopped by the mercs comming ruinning in with guns blazzing.
