Ethan Petus: Primative War

Primitive War has one of those premises that feels can't miss. Special ops soldiers in Vietnam. Dense jungle. Missing men. Russian experiments. Dinosaurs. It’s basically Predator smashed with Aliens, a little Apocalypse Now, and the DNA of Jurassic Park stitched over the whole thing like some blood-soaked science experiment.

This could have very easily been lazy “dinosaurs eat soldiers” schlock. Instead, Ethan Pettus gives the story enough personality and atmosphere that it becomes more than the sum of its inspirations. The biggest surprise is how strong the characterization is. These guys aren’t just interchangeable action figures holding rifles. Even when they lean into familiar archetypes, they’re memorable. You can picture them clearly. Hear their voices. Understand how each one reacts under pressure.

That matters once the jungle starts swallowing people whole. The dialogue occasionally slips into cheesy action-movie territory, but that feels intentional more than accidental. Primitive War wears its influences proudly, pure 80s one liner action dialogue. The literary equivalent of finding some beat-up VHS tape with amazing cover art at a rental store.

Once the squad pushes deeper into Vietnam, the book really starts cooking. The jungle itself becomes oppressive. Humid. Rotting. Alive. Pettus understands one of the key reasons Predator worked so well: the environment has to feel hostile before the monster even shows up. Every movement through the brush feels dangerous. Every silence feels loaded. By the time the dinosaurs fully enter the picture, the tension is already humming.

Then, enter the dinos. It kinda rules. It's not just because giant prehistoric creatures are ripping people apart, although that obviously helps, but because Pettus treats them like animals first and movie monsters second. They stalk. Test. Observe. The violence feels sudden and ugly rather than cartoonish.

There’s a sequence involving Gerald’s death that so vividly described. It reminded me a lot of the gruesome matter-of-fact deaths in Crichton novels, especially Hammond’s end in Jurassic Park. I could practically hear Scott Brick narrating it in my head.

What elevates the book above pure creature-feature fun is the underlying thematic stuff bubbling underneath all the gunfire and gore. Everyone in this story is becoming primitive in one way or another. The soldiers. The Russians. The Viet Cong. The dinosaurs themselves. The Russian collider experiments are pure Cold War arrogance. Tear a hole through time and space in pursuit of ultimate power without ever stopping to consider if maybe that’s a catastrophically stupid idea. Borodin casually brushing off the deaths caused by the experiments feels believable. Governments sacrifice people all the time when chasing superiority. The difference is dinosaurs make the consequences immediate.

There’s also a really strong parallel between Sergei and the predators hunting the jungle. The dinosaurs kill because they’re animals. Sergei kills because somewhere along the line he started enjoying it. Primitive War not so quietly keeps asking who the actual monsters are, and the answer changes depending on the chapter. That’s where the Vietnam setting becomes more than just aesthetics.

The jungle strips everyone down to instinct. Nationality stops mattering. Morality starts eroding. Survival becomes the only real ideology left. Pettus doesn’t hammer the metaphor over your head, but it’s there if you want to dig into it.

The final act goes full survival horror. The desperate push to destroy the Russian collider before the situation spirals beyond repair feels straight out of Alien Isolation in the best possible way. Claustrophobic corridors, hunted soldiers, constant tension, mounting casualties. The pacing ramps up hard and barely lets off the gas. Most importantly, the deaths actually land emotionally because the characters feel lived in beforehand. Heroic deaths sting. Cowardly deaths frustrate. Brutal deaths linger.

Overall, Primitive War is just great time. Fast, violent, tense, and way smarter than its premise initially suggests. It’s not trying to reinvent literature. It’s trying to deliver dinosaurs tearing through soldiers in the Vietnam jungle while sneaking in commentary about war, power, and human brutality.

Sometimes high art is great. Sometimes you want a T-Rex eating a guy in the middle of a firefight.
