As expected, trapping ghosts is the game's highlight, and developer Terminal Reality has nailed the feeling of wielding a proton pack. Wrestling with ghosts and trying to lure them towards a trap after weakening them via proton pack blasts is a fun, fishing-style tug-of-war. You can also create a fantastic amount of collateral damage, and use a PKE meter to find spooks and add their data to the Tobin's Spirit Guide. The sound effects are spot on, with the click and whir of the proton pack as it is flicked on particularly nostalgic. Better still, a lot of the dialogue is genuinely funny. Dan Aykroyd's genuine enthusiasm for the project is obvious from his lines, and (naturally) almost anything that Bill Murray utters is guaranteed to prompt a giggle. The forced scenario of the player as a mute cipher - a fifth Ghostbuster charged with testing new equipment - doesn't work as well, but lets the other characters strut their stuff unimpeded, whether in the lengthy cut-scenes or as co-op buddies during the action.
