The Weapon

Baf's Guide

In the aftermath of an intergalactic war, researchers puzzle over an abandoned weapon system vast enough to include stars as components. You're the only one with the skill to unlock its secrets, but no one trusts you near it. Thus, you face challenges from both the roomful of alien tech around you and your suspicious partner-cum-captor. It's like solving a puzzlebox while wearing handcuffs. Reasonably short. I found one of the puzzles obscure, but the built-in hints are thorough and gentle.
