The campaign is seven missions long and took a total of seven hours to complete. While most of that time was spent catching ghosts, you also have a few things to collect to make it more than just levels of ghostbusting and at times working out how to get out a room via a puzzle of sorts. The things you need to find are artefacts and ghost scans, which you do so by busting out your PKE scanner and pressing RT to scan. Artefacts show up blue on the equipment as you hunt around for them, as for scanning ghosts it's best to just bust it out to scan them every time you see a new kind of ghost. You also earn cash along the way which allows you to upgrade your equipment. This is simple enough to do and by the end I had all things upgraded fully without even trying, so I guess it's just something to make you feel like you're unlocking things along the way, while in truth the equipment never really feels any different unless you unlocking actually moves like being able to slam dunk ghosts into your trap.
In terms of sound and looks, it's a mixed bag. Sure, it perhaps hasn't aged well when it comes to how levels look and how basic they are, but the ghosts and even the Ghostbusters in how they look and sound are still an iconic thing. Hearing the siren from the Ecto-1 and the likes of the actors who were in the films add a lot to the game, with even the sounds of ghosts when just walking around making the game slightly scary if sat in the dark and some headphones on. But that said I am a wimp.
Overall: Mixed bag this one. The bland story, on top of AI ghostbusters who are nothing more than a liability, and combat controls which feel very dated make it very frustrating at times. But once knocking the difficulty down to casual, I can't say I never had any fun as I would be lying. No online will ruin it for some, but if you want a quick game to blast over the weekend then this will perhaps be one to take a look at.
