will i was watching 2012 and i was thinking how in the world will u r me kill a alien in combat nukes? guns? drop a car up 4000 feet in air on them? what would you do!
I think that might take too long to kill one, even if our diseases were physiologically compatible with them... It would work long-term, but by that time I'd think most humans would be dead.
If from Mars we can use bad music. If they are Cyborgs we can use a tommy gun on them. If from the unknown depths of space, we upload a computer virus to their mothership's harddrive. If they have super evolving abilities we use Head&Shoulders shampoo on them. We could always launch a missile into there exhaust port. Or simply just wait around for our germs to kill them.
If they are Cyborgs we can use a tommy gun on them.
Wouldn't cyborgs have external armored plating? .45 ACP isn't going to do much against tungsten or something like that.
The US Navy developed a rail gun(no, it's not just from Transformers), I would like to see that used, and an alien would make a good target. Or... I could just charge mah lazer.
