I've been working on this a little and here's a preview, I would like to know what you think.
"Go! Go! Go! Their right behind us get to medical!" The marines were in a dead on sprint running down the corridor. "It's just around this corner come on!". Ramirez slowed down to a stop "Hey guys hold on a second, I don't think they're after us any more. " Something started falling onto his shoulder, he looked up only to see a black figure above "oh shi..." It lunged down and grabbed him dragging him into a vent above "Ahhhhh! Help me, get this ugly mother off of me!" Seconds later his screaming stopped and blood started dripping out off the vent. "Noooo! James!" Jacobson grabbed him by his arm "c'mon we gotta go!" "No he's still alive, I've gotta help him!" Jacobson turned him around "He's gone alright, there's nothing we can do for him now but get our asses out of here! Now come on!". Beckett shouldered his weapon and gave a shaky nod. They both cornered the hallway and headed into medical, Jacobson quickly turned around and started welding the door shut behind the. "Do you think it'll hold?" Beckett asked. "I have no idea but we're about to find out. Hostiles closing, ten meters, eight meters, five meters...". Beckett got a worried look in his face "uh id hate to to rain on your parade but that's inside the room.". "Yeah I know that, maybe my trackers reading wrong. What have you got?". Beckett pulled up his motion tracker "Yeah, I got the same readings as you." Ah man what the fuck is going on here.". "I've got no idea but we need to figure ..." All of a sudden the vent beneath Jacobson burst open and he got dragged halfway through and quickly managed to shout "Beckett get the hell out of here! Get word to command... Have them send more... Men." Blood started spurting out of his mouth and he disappeared into the floor.
