About ABYSS

ABYSS is a challenging co-op horror game where you and your crew of Engineers must operate a submarine to navigate through the darkness of the abyss and repair beacons found in underground structures. However, not everyone on your team can be trusted, as there are Saboteurs plotting to sabotage your mission. Will you repair the beacons and complete your mission before the submarine runs out of power?

THE SUBMARINE

You and your crew must manage a nuclear reactor, repair broken stations, navigate the trenches and venture out into the deep dark as a team. However, things aren't as easy as they seem. The functions of the submarine are split up by room, meaning you will need top tier radio communication between players to ensure your survival and avoid catastrophe! But be wary, not everyone can be trusted to give you correct information...

THE OCEAN

To survive in the depths, you're going to need resources. The only issue? They're found on the ocean floor outside the submarine, so someone will need to make their way outside to retrieve as many resources as they can. Be careful though, as you aren't the only ones down there...

THE GOAL

As an innocent Engineer, your objective is simple: navigate the submarine through the underwater trenches, locate the facilities and repair the beacons inside of them before you run out of power!

But as a treacherous Saboteur, you must either eliminate all of the innocent engineers or sabotage the submarine to ensure they fail in completing their objectives, and luckily for you, traitors aren't the only threat in this game...

DEVELOPER'S NOTE

This game was made as a challenge for myself to see if I could make a game in a genre I am completely unfamiliar with over the span of 2 months, so I do hope I did a good job and you enjoy the game!
