What do you get when you combine space marines and aliens? Well, in addition to countless video games like Starcraft and Warhammer 40k... and little game called Halo, you get the greatest action/sci-fi movie ever made; surprisingly called Aliens.
In case you missed the chest bursting goodness of the first movie, here's the skinny: there was a ship with a crew, a planet, and an alien that literally fell out of a H. R. Giger painting. Then, everyone but Ripley (Weaver) died. The sequel picks up with space marines heading back to the planet, on a search and rescue mission because someone thought it would be a good idea to colonize the planet. Unfortunately, everyone died. So, naturally the space marines are sent in to investigate and bring back any survivors. That plan goes to hell in a handbasket when the marines discover an entire colony of xenomorphs. Surprise surprise, just about everyone dies. Ripley and Bishop set the station to self-destruct and make haste back to the ship.
In the final encounter, Ripley battles the Alien Queen while wearing a giant mech suit. What ensues is perhaps the greatest face off in movie history. Titans clash and in the end the Queen gets blown out into space when Ripley opens the door to the hangar bay.
There's something to be said about a movie that is still the inspiration for so many other films, games, and a mediocre spin-off with the baddies from Predator. If you haven't seen this movie, you haven't lived.
You better watch my movie!
