3876 AD: Corruption (Demo)

3876 AD Corruption (Demo)

Crash-landed on a mutagenic wasteland, you awaken as Commander Larson. The world is infested by corruption and rogue modification drones, they are nano-bots causing a dangerous form of forced evolution. Your only hope lies in a fortified military outpost, where survivors like the cybernetically enhanced Specialist Lana and the steadfast Commander Zane struggle to hold the line.

Coordinate artillery strikes, scavenge dwindling supplies, and uncover the dark truth behind the outbreak. Reclaim the region, restore order, and survive in a broken world where humanity’s immortality may be its last advantage… or its ultimate downfall.

-- UPDATE 09/20/2025 --

Big Announcement: I'm planning on releasing a new version soon, probably by the end of September! I know the current version is kind of broken and mostly unplayable, don't worry, this will change!

I've been working on a bunch of features to make this a much better experience! You can look forward to a real dialogue system, upgrades, improved combat, quests, and a lot of little things here and there.

Once I'm done, I'll go back to making regular YouTube videos to showcase the game, create even more in-game content (new stories, more quests and new locations), as well as many more lore videos! I hope this will help to increase traffic to this site and get more people to play the game.

Thanks for all the views so far, it means a lot to me!
