This game has it's ups and downs. On the "up" side, it was rather entertaining and at times, amusing. The cut-scenes had some laughs and the voice-overs were pretty good too. I found the controls worked well, as far as controlling camera and player movement are concerned. The "art collecting" was fun...kinda gave you a little something to do on the side while you played. In the game you never really "die". Someone always revives you when you're weak, as in turn, you can revive others as well. Not really sure if that's an "up" or a "down" but, whatever.
On the "down side", the story-line sort of lacked meaning and was unorganized. I didn't really pay much attention to the "story", if that's what you want to call it. The controls for changing weapons was very simple and this is a good thing because, especially in the later stages of the game, you have to switch weapons A LOT!! Many enemies and almost all of the bosses require you to hit them with various weapons at various times. I was often confused by what I actually had to do to defeat many of them. The other characters in your group would often give you hints on what to do during battles, but their "voices" came through so weak in volume that you couldn't really hear what they were saying. And, you were generally running around concentrating on other things at the same time, making it even harder to comprehend them.
Overall, it's a good game to rent. It's actually quite easy to beat but at the same time it's pretty fun. There are bonuses to be unlocked and so-forth but, I didn't keep it long enough to do any of that. In my view, only die-hard Ghostbusters fans would perhaps consider buying this game.
