Among Us Xgameruntime.dll -

The DLL was small. 87 kilobytes. Its only export was a function called RunGameLoop_Imposter . Inside, the assembly was clean—too clean. No inefficiencies, no comments, no debugging symbols. Professional. And deeply, deeply wrong.

On her desk, her phone still glowed. Open to the Among Us subreddit. A new post, timestamped one minute from now.

Sofia swore she’d never seen it before.
