You’re moving with your best friend to the city of Kredon, home to some of the best schools and universities in the country, to continue your studies. However, in Kredon, there’s only one thing everyone talks about: ETERNUM—the virtual, hyper-reality MMORPG game released a few years ago that revolutionized the world of technology.

With a neural implant that recreates the five senses, it becomes impossible to distinguish between the game and the real world.
Thousands of servers form the network of Eternum: from colorful, magic-filled fantasy worlds to foggy sci-fi cities, no world is beyond reach.

Nevertheless, looking beyond the surface, there’s a darker side to this pretty facade: black markets, torture, rape, illegal content trafficking, unlawful assemblies, data theft… Eternum follows the rules of no man.

For some reason, governments turn a blind eye to this; there’s no regulation and no control. Some say it’s because the game is highly addictive, some say it’s because the market moves millions of dollars daily, some say those in power have been bribed, and others say… there’s something else going on.

And you? What’s your role in this story?

Well… That’s up to you now.

Enjoyed Once in a Lifetime so downloaded Eternum. My only complaint. I finished v.01 and can’t wait for the next version to come out. The developer looks to be committed to it and if stays ambitious – the sky is the limit on the scale of fun this game can bring.

Only the first version and already this many content? Amazing job as always by Caribdis. Even Stabby Mike got a sort of cameo in a dialouge. I’m excited for the rest especially with his games’ type of humor. Definitely gonna be worth the wait.


Downloaded it yesterday and finished it today that doesn’t mean it’s gameplay is short. For v0.1 this got fair amount of gameplay actually more than that. I was really waiting for a game like this. And this is from Caribdis this guy is a legend. Top notch renders and animations really looking forward to play next update. If anybody know similar games like please recommend it

Look Who Is Talking

I Like once In A Life…I Don’t Like This One To Short..I Thought It Maybe 2 Or 3 Gb Game But It’s Not…

Look Who Is Talking

It’s Need An Huge Update And More Like Once In A Life


Bro, it just only been v0.1 but still have a lot of content.


Its only the game’s first version and what do you expect. Even though it got more gameplay. Once in a lifetime almost took 2 years to complete. So you are looking to play like that play the game after 2 or 3 years when the game is completed.
