Extend the Story - Add a Room

You half jog half run over to the reactor level, You could hear the faint sound of gas leaking.You open the door and your jaw drops.
engineers are running about shouting things with a sense of panic in their tone.
"What the hell is going on?" you say to the head engineer
"Somehow an underground earthquake shook the reactor pretty badly,some wires and conduits have split, the main pipe used to cool the reactor has split in to,its beggining to leak radiation,we may have to evacu-"
the front of the reactor suddenly splits,you dive out of the way as gas engulfs the engineer, he screams, skin falling of untill he falls over next to you,blood pouring from his eye sockets,dead.
"Everybody evactuate!" an engineer yells, he presses a button and an alarm sounds,the huge doors slowly shutting.
You get up and run of the door sliding under it.
Not knowing what will happen next,you have few choices...
