Medium, but not mediocre
I've seen games 3D far more better than this, I don't remember the name, is dead space alike, you have even a flashlight... but the story entertained me until I win... so, you keep me playing.. is a ok game ;)
Thing I hate: have to reload everytime you get in a new room, and once you get the machine gun... you already make it to the end.
Thing I like: the donkey kong boat was a nice idea... the storyline is not that great, but at least is consistent. I think I see this prison storyline in other game tough...
