Aliens: Colonial Marines is not a very good representation of the source material and even if you strip away the Aliens coat of paint, this is just a very average shooter that fails to impress.
Aliens versus Predator Classic 2000 is a fun action-packed sci-fi romp, even if it is a little rough around the edges. It seems to cater more towards fans of Aliens than Predator but the representation of both is rather well done.
Turok 2: Seeds of Evil is a fun and violent first-person shooter, originally released for the Nintendo 64. This remaster is by far the best version of the game.
In no way does Broforce take itself seriously. What it does do is pay respect to the action movie genre in an awesome fashion. Blast your way through thousands of bad guys, aliens, and demons, on a mission to save the world.
