Embryogenesis

You've woken up to a changed world. Maybe you did sign up for cryonic preservation, maybe you did not: either way, the facility you've awoken within is under attack. Do you stop it, or do you run away? Discover what has become of humanity after corporations were allowed to go too far, and Artificial Superintelligence has done its damage.
Cooperative Multiplayer
Do you go at it alone? Or do you go at it together? Do you split up and solve problems separately, or do you combine your firepower to handle the onslaught of machines?

Or, perhaps, do you revive every friend you possibly can in an attempt to completely overwhelm your opposition?

Explore a Devastated World

Explore the cryonics research laboratory where a subset of humanity is preserved, a shelled out underground military bunker, the devastated remnants of the mountaintop that housed both, a forest laden with clues pointing towards what's left of humanity, and more.
Momentum-Based Movement Mechanics
Found a steep slope that you slid down? Carry that velocity with you. Have a rocket launcher? Rocket jump! Embryogenesis has a weapons and upgrade system designed to let you go as fast as you can handle - until you smack into a wall. Or some other, more angry piece of metal.

You, Yourself, Can Save Humanity
Customize your character however you'd like - import your own character skins or use the built in options to create your own character.
