Her hand hit the door switch, but nothing happened. She pressed it again. Still nothing. She would have tried to pry the door open, but with only one hand free, that was impossible. Still, she could always blast the door open. That was assuming that the Kriken would let her.
The Kriken slammed into her side, pushing her away from the door. Samus slammed into a wall, leaving another dent of her shape in it. That little insect wasn't making things easy on her. She would have to dodge it while trying to shoot the door open. Samus checked her missle ammo to see if there was at least one left. There were five left. Just enough for a super missle. Perfect.
Samus looked up just as the Kriken lunged at her again, held up her left hand, and balled into a fist. It's face flew smack into it, satisfying Samus with the sight of it's exoskeleton cracking. She wiggled her hand into it and yanked, hard. Samus had expected to tear it's head off, or even tear a larger crack into it's face, but only succeeded in throwing the being towards the hole through which she had come. Good enough.
Samus leapt from her dent in the wall, and into the air, hoping to land a super missle on the door. But the Kriken came back. It latched itself onto her arm-cannon, and dug one sharp tipped arm into the nozzle. The auto-diag in her suit registered the weapon as being jammed and shut it down. Samus swore. It would take four minutes for it run another diagnostic and then restart it. Samus checked the timer on her air. Four minutes, and five seconds. It was going to be close. Damn close.
Both of them laned ina heap on the floor, stunning them for but an instant before Samus regained her attack posture. The Kriken remained securely attached to her. Anger driven adrenaline pumping through her, Samus brought the useless weapon down upon the creature's head, and was yet again rewarded with the sight of more exoskeleton falling off. But it didn't let go. Instead, it tried to get even with her, attempting to puncture her visor. Samus responded by kicking it in the chest, making it revert back to it's normal biped form. She followed up the attack with another kick to it's face. But it had recovered by then, and grabbed her foot. It then proceeded to flip her around, and swung her into a workbench.
While in mid-air, three feet from the workbench, Samus fired her grapple beam, and used it to drag the Kriken with her. Flailing around in the air for a moment, both of them fell to the floor, smashing the wrkbench to pieces. Both struggled to keep the other from getting up. The Kriken held her by the throat, and she had it by the head, still hoping to pull it from it's neckless body. And she did. Her arms jerked back, nearly throwing the head, and the being's body instantly went limp. Samus pulled it's arms from her neck, and looked into the lone eye of the alien face, glaring at it. It had tried to kill her, and it had failed. Or, at least, that's what she thought. As she cast the head aside, the thing sprouted legs. It crawled along the floor, heading towards it's body despite Samus' attempts to smash it. Samus checked the status on her weapon, hoping she could fire it up and destroy the body. But no such luck, two minutes still remained until recharge.
The Kriken was back up now, only it's head no longer floated in space without a neck. The legs instead held it onto the body. Clearly it had decided to take caution. But not enough. Samus lashed out with her grapple-beam again, grabbing it by the head, and yanked as hard as she could. The Kriken anticipated the move, and grabbed a nearby desk with it's feet, allowing Samus' own stregnth to shove it in her direction. The Kriken had probably hoped to make her flinch and release it, but Samus refused to be intimidated. She continued to pull on the Kriken, dragging it with the desk towards her, knowing full well what she was doing.
Right before the desk and Kriken hit her, Samus switched to morphball mode, allowing their momentum to ram them into her. A small shockwave extended outward from the point of impact, and the desk exploded into thousands of shards. Among them were pieces of Kriken exoskeleton. Samus, now out of morphball and on the other side of the room, watched the cloud of miniscule debris carefully, keeping an eye out for any kind of movement. She didn't take her focus away for a moment, only sparing a tiny glance at the timers on both sides of her visor's HUD. Forty seconds until her air ran out. Thirty-five seconds until arm cannon rearmament. She waited for her enemy to resurface.
Thirty seconds of air left. Twenty. Fifteen. Ten...
The Kriken flew up out of the ground, punching a new hole in from the room below. It's chest was torn open, damage from Samus' bomb, a scab of frozen black blood the only thing keeping it's organs in. The angered being lunged at her again with it's sharp tipped arms, this time aiming at her heart. It wanted to do to her what she had done to it. But Samus knew that with revenge came blindness. In the moment before it would have struck, Samus lunged her arm cannon foreward, and punched it in the gut. The injured insect flew across the room, landing in front of the door. It had enough strength left in it to look up just in time to watch the super missle pierce it's face, and burrow through to the door beyond. The brilliant explosion forced Samus to look away. Metal shrapnel flew across the room, along with the remains of the Kriken warrior. Samus started to smile until the warm blast of air from the corridor... didn't come. Panicking, she ran to the door and stuck her arm through it. There was no forcefield, no magcon field, absolutely nothing to keep air from coming in. The air that she so desperately needed, simply wasn't there.
They vented it. They knew I was out of air. It was the only answer. Why else would the room be full of air when she came in, but the corridor outside be devoid of it?
The timer ran out, and a constant beep noise filled her ears. Her last hope, faded into despair. Soon, what little air in her power-suit would be used up, and then... It would be over. The last thing Samus saw, was the reflection of a blue light in her eyes. Then she blacked out. But it wasn't the usual blacking out sensation that she was used to. It was somehow different this time.
