Do you like first-person shooters? Do you like giant mecha? DO YOU LIKE DINOSAURS? Then Orion: Prelude may just be for you.
I’m in two minds about this multiplayer shooter from the ORION: Prelude team that somehow isn’t ORION: Prelude. Is ORION: Dino Beatdown a brilliant name for a game, or is it a horrible name for anything? One thing I do know, despite the laudable presence of dinosaurs and jetpacks, I’d be a lot happier if the dinosaurs were actually using the jetpacks :D

Everything in Orion is a little…bland. That isn’t to say that the game is rendered poorly, but it all just looks generic. Most of the dinosaurs and vehicles look good, for what they are worth, but some of the guns have not received as gracious a treatment. For example, the shotgun looks more like a rifle and has a really ugly ammo counter on it that just looks tacky.
The dinosaur models look just fine, but that isn’t the problem with them. They are often poorly animated. For velociraptors and “compies” the jump attack just looks silly and the bite animation is more a head twitch than a vicious attack.
The vehicles are frustrating to drive yet are grossly overpowered. Most dinosaurs, baring the large ones, you encounter can simply be killed by running them over. The rest will immediately destroy you vehicle for some unspecified reason.

The basic survival mode gets you through 15 waves of defending a generator and buying guns, but lacks any form of climax on the last wave. An evolution of this mode is Conquest , where you defend three bases consecutively and additionally, you can buy vehicles. It is basically three times Survival, but the game gets a lot more interesting with limited funds available – money sharing gets very important here.
The game feature actually 14 game modes.

Only in some modes you actually get to play as all the dinosaurs you normally fight. This part is actually pretty cool. You play as the dinosaurs in third person. Some of the gems in this mode are playing as a t-rex, raptor, and spinosaur. You can even be a deinosuchus (40ft long crocodile), which is pretty rad. But hey, how many games can you actually play as a dinosaur?

I am being pretty hard on this game, but despite all the flack I am giving it I still LIKE IT for some reason. It is just fun to play in its own quirky way. At the same time, I feel like the studio behind it might actually be able to polish it to a degree that it becomes a decent title. This is the 3 update now? Every update, the game is much better and the price drop down. 0,99$ is it today and at the halloween special the developers give the community 1000 FREE copies of the game. thats awesome :)
Overall, i almost feel like it is one of those games that is so bad it becomes good. 75% of the steam reviews are good, try it out and dont hear at the meta critics!

Sorry for my bad english. This is my review account, because the low playtime.
Thanks for reading! If you Like my Review, give me a Thumbs up in Steam.
Your help is greatly appreciated :)

Like a 79p donner kebab, but then you get mugged and someone steals your dirty uncooked kebab and instead gives you a knife wound which lets you go to hospital and have some lovely hospital food instead of a poisonous kebab.
EDIT: Duck you Tryyton

Ah yes, Orion: Prelude, or as it will always be known to me, Orion: Dino Horde! This game has been quite criticized through the years (and in all honestly quite rightly so). they game if filled with bugs and lots of tedious grinding achievements. Still, despite all that I can't help but to love it. In fact it is the only game which I haven't uninstalled after reaching 100%.

So, there's no story to follow in this game and it's a pretty straightforward king of game. You're dropped as one of three classes (assault, recon and support) into a base where you're supposed to defend a generator against incoming waves of attacking dinos that don't enjoy your presence there. If all teammates dies or the generator is destroyed (a timer starts when it reaches 0% health and if it isn't repaired before time runs out it's destroyed) you all loose. If you survive all waves (10 for normal games and 30 for conquest games) then you win. Pretty simple. To your help you can buy a quite big assortment of weapons and perks and each class comes with a specific perk of their own (assault can jetpack, recon can cloak and support can heal).

This game has a lot of various pvps but there are only a couple which I really enjoy such as king of the hill and team elimination. The place where this game really shines is in regular Survival mode when you play together with a good, tight and cooperative team. This is where this game is at it's best! I don't think I've made as many friends in any game as I've made in this one.

So, in conclusion, if you want a good cooperative game and don't mind a few bugs here and there and can either ignore, or work through all the grinding achievements then yes, you will enjoy this game!

This game...if people from the future got in an accident or traveled back in time, or the dinosaurs somehow built teleporters to the future, Orion: Prelude would be the result. It has good graphics, but I get a feeling most people turn down all thier settings so they can actually see the dinosaurs. Extremely buggy, it feels like this game was made for a console and not the PC. However, you don't often see an fps game go for a buck, either that or its a freemium game. Good for maybe 2-3 hours of fun, but don't invest too much time into it, it's not worth it. A very easy way to beat waves is to use the assult class's jetpack to fly onto the top of a tall rock, and stay there with some form of sniper rifle. Dinos can't climb for ♥♥♥♥. Just look out for the flying dinosaurs, they can still get you from above. It DOES HAVE HATS, but don't worry, it will never be a het simulator like tf2. Oh, and it has trading cards, so there's a plus side to it I guess.

Think of it this way: A bag of chips at the airport would cost twice what this game costs. Over the long run, this game would probs be the bettah deal.

Just remember kids, one does not simply run this game at high quality.

For $1, this game is worth ever pennie of that! Fun to play Co-op, as well as solo. Two down sides are; 1, you cant play on the mac (So to all mac players, get a PC :P ) and 2, no mission. However, that doesn't change how great this game is! You'll find that many of the negitve reviews have poeple saying "lag" or "glitches". This has nothing to do with the game and only requires an updated video drive for their pc.

So buy and enjoy the game.
Good hunting! (Surviving)
