Prequel to Prelude - 'Guardians of Orion' - Now on Kickstarter!
Dinosaurs, Robots and Dragons are now on Kickstarter!

My name is David Prassel. I am the Director here at Trek Industries, Inc, creators of the indie multi-platinum hit, 'ORION: Prelude'. We are extremely proud of what ORION: Prelude has become and we are now ready for the first time in over half a decade to tackle our next project, 'Guardians of Orion'

"The Prequel AND Spiritual Successor to the multi-platinum indie hit, 'ORION: Prelude'. SNES-inspired gameplay on Next Gen Tech!"

We have just launched our Kickstarter for 'Guardians of Orion'. We are back to show you what Kickstarter is all about, and that is the BACKER, the people who help back and create all of these packages. I am tired of all these gimmicky campaigns, non-rewarding tiers and we are going to change it with action. We will have the best $1 tier in Kickstarter gaming history.

We are video logging every day of the campaign:

Love these devs.

Not to often you see a dev making fun of themselves. "In 2012... We released the worst game ever"

The game is pretty fun overall, glad i got it to support them :)

ORION: Prelude

This game is like junk food. You know it's not the best quality, you know that you have over a hundred better ways of spending your time, and that's excluding your vast library of games, but you...




What is this game about? It's exactly what it looks like. You are going to shoot that raptor in the face. You are going to get in a big stompy mech and force-feed a T-Rex a rocket sandwich slathered with molten lead. You are going to pistol whip a pterodactyl that's been annoying you for half the wave.

All of this, for less than it costs you to buy a soda.


Now, onto the useful bits of this review:

This game is geared towards five and ten-player matches. While the game offers a wealth of game mode options, you are primarily going to be concerned with PvE content, or Conquest and Survival, both of which are co-op.

Straight out of the door, you are equipped with a pistol, and absolutely nothing else. There is a minute of downtime each round in Survival/Conquest, in which you can buy weapons and augmentations for your character. Pistols will never run out of ammunition. Secondary weapons consist of SMGs and shotguns. Primary weapons are automatic rifles, sniper rifles, and burstfire rifles, all usually with some form of scope for ranged shooting.

Augmentations are permanent upgrades for your character that you buy with credits from killing dinos. Three augmentations are specific to your class, while the rest beef you up as the going gets rough.

There are three classes in this game: Assault, Support, and Recon. Assault players have access to a jetpack with a generous amount of energy to use to get in hard-to-reach spots. Support players are equipped with a Medigun, with the ability to heal (and, with an augmentation, repair) other players and vehicles, as well as the ability to self-heal with right-click. Recon players have access to cloaking devices, allowing you to shed off your attackers as you run like hell slink away into the darkness.

Adrenaline weapons are power weapons, supposedly unique to each class. It is worth saving up the credits to get one, trust me.

Progression. This game has progression for yourself, as well as your three classes. The more you play, the more permanent upgrades you get for them. Things like 10% higher jumps, available weapons on spawn in PvE modes, and so on.

Now, here's the thing. This game is, for better and for worse, a tad wonky at times. The menus aren't snappy, the third-person animations are offensive (and, in the case of certain taunt packs, deliberately so), and the game isn't exactly Crysis 3. The game also has cosmetic microtransactions (gun skin, armor color/skin, silly hat, cape, and taunt pack), but the vast majority of the items available are as cheap as $1. You know, like an actual microtransaction. This would normally be a huge turn-off for me, but the game's price allows it some wiggle room.

TL;DR: for the money spent, this game serves as a good distraction, especially if you're not fussed about a sci-fi shooter in which you reenact the meteor that extinct-ified everything.

Dinosaurs, jetpacks, lightsabers, teleporters, invisibility, high-tech vehicles, extreme weather effects... omg this game is everything! And epic victory music is playing in the background all the time. Seriously I have really good time playing this game.
