“So, what is this game like? Halo + Turok + Killing Floor. You’ve got your standard pistols, machineguns and shotguns and then you get your rocket launchers, laser guns and heavy weapons. Each class has their own special abilities like Jetpacks, cloaking and healing beams, all which can be augmented to be more effective. You can also level your classes for better performance like in Killing Floor which lifts the burden of having to buy certain augments and use that money for other things. You’ve got player vs dinosaurs, player vs player dinosaurs, player vs player, player vs harder dinosaur waves and Conquest which is coming up soon.”

“O:P reminds me a bit of those classic, simple shooters like a Serious Sam or Left 4 Dead, but with a bit of high-tech sci-fi flavor. This future-tech feel across the game contradicts the jurassic era dinosaurs & remote wilderness landscapes nicely! O:P is not as complex mechanically or technically when compared to a top end AAA FPS, but its simplicity is also its underlying strength. It is great value ($1!), has strong replayability and the focused, balanced gameplay(some bonus ..ahem.. querks) offers a truely fun & intense, dino killin’ co-operative survival experience!”

“This game started as disaster with a good idea. With the newest Update a lot has changed and it needs a review from all the bad voters…. it tooks a while but the devs made the effort to finish their product (not like many other bigger studios out there) Worth gaming. Worth buying.

“You can fight a T-Rex in a mech. That’s all you should need to know, unless you live a small, sad existence.”

“I played this game on a 3-day weekend in 2013, I can’t tell you how much I absolutely loved the game.

Recently I’ve been thinking back to it and wondering “What am I doing with my life to not have baught this yet?”
Then it hit me, I NEED to buy it, so I did and it was the best choice I ever made, the game is amazing, and insanely fun to play.

For anyone who loves epic battles and insane weapons, I reccomend you buy this game immediatly.”
