I thought this game was frustrating throughout (especially with the lack of saving whenever).
Although it grew on me.
What I like is the consistency of the graphics which are some of the best I've every seen.
The high points are the boss battles because this game has probably the best ever VG gameplay to date. The gameplay mechanics are highly sophisticated and the whole experience (through the visor) is very immersive when fighting the(bosses). You truly feel as if you are in this world inside the spacesuit.
This is not for the lightweight gamer though.
I would give it 9.0/10
because the boss battles are just the best I've ever played.
