I wouldn't say it's terrible, but those review scores are absolutely ridiculous. At best it deserves maybe a 3/5 on the Netflix scale.
It's worth $7 though if you've already played Dead Space 1 (though bear in mind this is a much worse, much lamer game, though still not completely worthless). I suppose for lightgun style game it might be the best one ever made, which...is not saying much, but...
Though yeah, if you've got a Playstation, just buy Dead Space 2 and get a better version of this with that.
Well, I like light-gun games and sadly, have yet to play a really good one. Time Crisis 3 was okay and House of the Dead for the original Xbox was okay ... but problem is most of these games are SO campy that it's hard to get into.
This one actually seems like it takes itself seriously, which is good. Graphics look okay (this is a Wii game, after all), and for $7, it looks like a lot of fun.
