The whole game was one long lonesome walk for me unfortunately.
Dead Space 2 gets its acclaim from its looks they are super slick and the sound is brilliant as well. The story is essentially AAA you start at A walk on treadmill for 18hrs to point A then the Apocalypse happens. The plot is... light: I woke up with amnesia in a space station where everything was going to hell.
Reality is at times smudged to make way for some very abstract level design and npc's one strong example is the baby humans crossed with banelings (their existence due to a dare between the developers, can you believe?) in a day care that looked to be borrowed from the set of Stephen Kings It.
It's an 18 hour romp around the intergalactic space metropolis and thankfully the developers throw in a bit of humour at this:
Ellie Langford: "theyre swarming into the medical bay. At least you wont have to go there."
Tram computer: "Unexpectd obstruction"..."Welcome to the Medical Bay"
Isaac Clarke: "ah crap"
Isaac is constantly deviating from path which is fine as it doesn't side track you and it helps mix things up a bit. My end didn't bode to well I am a little annoyed, maybe I could have stomped on and dismembered a few more enemies for loot throughout the game I just found it tedious tbh. The lead up to the final battle sees a new npc that cant be killed which I am guessing is supposed liven up the game-play, it did but it was a fine line between challenging and annoyance. It did work well in being scary though having this monster track you down constantly rattling and scowling behind you.
Conclusion: Dead Space 2 has some really weird design choices that will leave you questioning why you played this boring game at all.
