Game has been abandoned - not updated for over a year. Do not buy14 found this helpful
The only thing you'll get from this Serum is a bad case of the Early Access blues... It's abandoned.10 found this helpful
I wanted to finish the game, but sadly, I hadn't gotten very far when I got the message: "The UE-Serum Game has crashed and will close. LowLevelFatal Error. This package may be corrupt!" immediately. So what should I do? Quit this game and play another3 found this helpful
Dead Game - Abandoned2 found this helpful
Was super hyped for this game and took the chance on an early access release. What was there on release was really good! I think the Devs abandoned it, last game update was May 2025. Hate to see it, but don't buy it unless they do a full release with major updates as the last I played, even the story wasn't complete.2 found this helpful
Runs so poorly I couldn't even play it, even on the lowest graphics settings.1 found this helpful
