If you think you’re getting lost or don’t know what to do, it’s okay to follow another lead. Sometimes the solution will come back to you. The signal scope is your friend when finding a new lead, and the ship log is your best friend for tracking it and figuring out what to do next.
I hope you enjoy it, it’s a game you can only experience once.
I don’t play Hitman in short bursts, but I think you certainly could. The sandbox is there for you to figure out and mess around in. As long as you get your target killed and get out, it doesn’t matter if you did it quick, slow, in a clown suit, or just happen to kill every other non-target NPC in the map either.
