xtro ii represent the second encounter have nothing to do with the first xtro mainly because the director have the right to the name xtro but not the story of the first film so they could have any type of alien scenario and make it a sequel to xtro and this be why the xtro film have no connection between each other and why the alien be different so xtro ii be a completely different film to the first xtro . the plot be about a group of scientist that have create a dimensional gateway to another universe call the nexus and three people go through the gateway while the scientist watch through a camera on their suit . they see some weird thing in the distance and go towards it then suddenly their camera shut off and theyre trap in the nexus and so they call for a group marine and a scientist that have be in the nexus to go the base and they arrive their and later on the gateway open with one life form detect . of course the woman that have escape have one of the alien in her and soon it burst out of her ( just like alien ) . then the marine go around search the base for the alien while it slowly kill them off . xtro ii be a mix of alien and alien and even the one weapon that marine us be similar to the smartguns use in alien and the alien itself look a bit like the xenomorph in alien . i do enjoy watch xtro ii represent the second encounter and if youre in to low budget sci fi horror flick then check xtro ii out for some alien copying fun . positive .
