Hard

In these games, guidance is minimal and the intrusion is messy (just like real life). You’ll sketch a plan, pivot across data sources, validate each finding, and adjust on the fly. Expect fewer hints, more strategy, and satisfyingly hard-won answers.

Don't Bother

Fleeeee!!! I mean, err... You’re driving the whole investigation—scope it, hunt it, prove it, tell the story. We give you the case; you deliver conclusions backed by evidence and a clean narrative. Expect portfolio-ready work and the “I can handle new stuff” confidence that senior analysts rely on.
