Heres the movie.
Two people were alone on a planet and were attacked by aliens so here's the 6 survivors of the attack on earth on the same day. Oh they vomit acid and and their blood turns people into them, but also gives some LOTR themed exosuits. Let's get the fall guy for last time we used a bomb that creates a black hole that eats a whole galaxy (that was for some reason used on rebels before) and get his opinion. Oh he feels bad and regrets using it before? It's cool he's all for using another one. Let's use a worm hole to get the the last place that was attacked by the aliens despite the first contact being like an hour ago and the only "survivors" now being dead on earth. Should be a safe trip as long as there's no traces of this stuff that the person operating the warper just said there was alot of in the area. Fly through a random space battle of people vs infected people maybe? Land on the planet without any ship, find out people have been fighting them on the planet all day and then there's a 5 second interaction with them and thinks they aren't totally dangerous? Nah its cool a missing character shows up infected and tells them they want war (even though the infected dont talk, no one questions it) so sill going to bomb them. But how do we stop the back hole from killing us too? Well there's a guy stuck in space with some fuel left in his exosuit which should be enough to blow up the massive portal that the blood bourn space parasites built without bodies so all we have to do is hit the person exosuit with a huge missle which should be able to blow it up. 6 days later it's time for drinks at the bar while the space alliance acknowledges aliens bad.
