The next movie should be real fast because dinosaurs can be hunted easily
Honestly, the problem all these movies have is a lack of appropriate weapons. Blue was taken down by a bullet to the leg, right? All the others got tranquilized. They obviously sedated them before to get them on the ship in the first place. They still have the tracking chips in them, so it's not like they can hide. Just do it again and roll credits.
Worst comes to worst, toss a tank at them. Get one Apache helicopter and shoot them from a distance with M230 chain gun. These things would drop like flies. Get an RPG to take out some of the others. I can get my father's deer hunting rifle and shoot some of these guys in the head from a distance.
