Screamers.... now that is a nightmare of a movie.
In the not so far future (2078) a new source of energy was found, berynium on some rock probably in the middle of no where. It looked to be the best thing since coal or sliced bread judging by the intro. But after awhile of mining for it, the process started throwing up huge amounts of radiation. To stop it the workers and scientists banded together to put pressure on the company. Who in turn launched an all out war with the Alliance.
After being Nuked half of the planet... can't blame them for needing every last trick in their book to hold on. They invented a monster, the 'Screamer' an Autonomous Mobile Sword. That tracks targets by their plus and use the cutting buzz saw like blade that makes up most of their body to cut the enemy to death. In the opening a N.E.B. (the company) grunt trying to deliver a message got a leg and an arm chopped off before the screamers finally lopped off his head. Built by an automated factory under the Alliance bunker, they proved valuable at protecting the base and stopping the enemy. The only way they could tell friend from foe required you to wear a 'tab' on your wrist to block their sensors. When the poor sap with the message came in it was their first N.E.B. contact in like 6 months.
After the journey to respond ensures (hey I'm not spoiling the entire picture:-P) two Alliance soldiers, a green kid and a seasoned local. Meet up with a new and improved version. A little kid claiming to be a survivor in the waste land, begging to come with them. The trick? It's really a droid, so real you'd think it was human - once it get's inside the enemies bunker. It releases it's payload, a deadly 'Screamer'. A N.E.B. squad they link up with tells how effective it was. The droids murdered most of the N.E.B. forces inside their command bunker during dinner time. Also another model...
A wounded soldier begging for help, go to help him and vola ! You're ripped apart by the screamer. The things we're self manufacturing as far as the viewer is able to gather. And some how self improving, more advanced models developed by machines, as it was stated that none we're sent to the planet from command since the prototype years ago. When the scientists effectively built the factory, pushed the on button and ran like heck. In the N.E.B. base they found another model, simple lizard/reptilian like screamers. Slow walking but flast leaping buggers with a Dinosaur like look & feel, right out of a museum.
When the merry band returns to the Alliance bunker... they find out the same thing that happened to the N.E.B's destroyed the soldiers there. The voice of the bunkers 2nd in command beckons them in over the radio. A repetitive conversation and multiple personality show its a trap. Faced with an Army of droid children clutching teddy bears and having a screamer inside marching out of the base. Trust me it's not as corny as it sounds lol. Using their high powered by todays standards weapons til the ammo ran out. Then dropping down to the built in flame throwers... They couldn't hold off the onslaught. So using a recovered micro-nuke they blow the place to crap.
Only to discover one of the N.E.B's with them injured, when the green Alliance kid goes to help. He's ripped apart by the advanced screamer... horrible, not even the 'tabs' worked any more. The Screamers now could kill any one and every one. After being put down the last two people left, The Alliance commander and a N.E.B. woman set out for the one way off the planet. The 'oh crap the place is about to explode' escape system for the bases commander.
To prove that she is human the commander nearly cuts the womans arm off. To do like wise he almost does the same to his own hand before she stops him. The two apparently falling in love head out, only to be greeted by the commanders friend and the next in the Chain of Command. Another screamer !! The screamer was said to have cut off the mans face and took it, hence the appearance. After disposing of him they find another horror, the escape shuttle only has room for one.
Pulling every trick in the book the commander tries to make sure the N.E.B. woman is the one to go, yet theres some reason why she "just can't go". When a duplicate shows up, we know why ! Another screamer... the most advanced yet. The two fight to the last fembot standing, the victor gets a blast of rocket engine as the other dies. Leaving the poor guy to use the shuttle and hope he gets back to Earth... and meets HUMANS !!! It's made clear that his and the fate of earth may be undesirable...
You'd have to see the movie to really appreciate it but it is really horrifying. Man kind is deadly enough without machines surpassing us. The screamers evolved to the point that they killed their own side. Then to the point that they killed each other. It's pretty dang sad when your own governments weapons try to kill you !
I hope that People are never removed from war, unless war is removed it self. One can argue that there is no such thing as 'honor' in a war. If one see's the goal as to live to see the end in victory. That's one thing but there is some point. Where a line is crossed, it's not a matter of honor or fairness but of right or wrong.
Killing the enemy is one thing but murder is another. In screamers you can't tell if the person next to you is on your side or even human. The chap you've played cards with for the past year might try and rip your arms off the next. It's a sick idea... when machines have evolved past their creator, all but destroyed their creators, and start killing themselves too.
The Terminator is a scary idea but this is worse, just watch the movie and you'll find out why lol. I think it's a good thing when you can have some one sit out of the line of fire. Control a robot and have it drop a bomb on the enemy, thats good. But when your toaster oven is modified to kill the enemy while you go on a smoke & coke break. You're going to be pretty dang sorry if it tries to kill you after getting an upgrade !
