There's something nasty stalking Arnie and his group of commandoes in the jungles of Latin America, in this highly enjoyable 80's Sci-Fi/Horror/Action pic. As Colonel Alan "Dutch" Schaeffer (Arnold Schwarzenegger) and his elite rescue team are brought in to locate the occupants of a helicopter crash, who dissapeared somewhere over the jungles of South America.
Following a spectacular battle at a Guerilla encampment, they head off to their pickup point, but soon realise they're being stalked by something sinister, as 2 of the team are slaughtered by an unseen force, which vanishes into thin air.
Knowing that they will never make it to the pickup point alive, they decide to make a stand to see if they can defeat the creature that's been stalking them. Which turns out to be an alien life form, boasting all manner of high tech gadgets and weaponry, that enjoys hunting humans for sport.
Some fun battles subsequently ensue, as the group tries to make a stand and this creatrure proceeds to make mincemeat of the lot of 'em.
Probably one of the best examples of a film that successfully combines horror and science fiction with plenty of rousing action, there's also a great cast, which includes Carl Weathers and WWF Wrestler Jessie Ventura. If you liked "Aliens" or "Starship Troopers", you'll have a blast!
