Apart from the tricorder puzzles, this is just a worse game in every way. Everything that made the first one so charming is basically absent. The weapons are less satisfying to use, the story is dumb, Munro is now an arrogant snob (you can't choose the gender either), and then there is this god-awful mouse smoothing and acceleration that makes aiming absolutely diabolical (and no, you can't disable it). On top of all that, the levels just consistently devolve into grinds. Every time you're introduced to a new mechanic, be warned that it will not be utilized with restraint as you progress. Rather, it will just be ratcheted up to the nth-degree so you can be miserable and feel challenged.
