Having Dead Space 1 gambled, of course had to Dead Space 2 ago. It has not much changed between the first and the second part, the only one no longer mainly fighting on the ship, but in the city. The story around DS2 is good, in relation to Dead Space 1 but weaker. At least it seemed to me, as it no longer were so many Audilogs. It also does not feel like a sequel to one game, but more like an addon (though the play time is good 11 hours). To complain that has taken the creepiness and has become action-packed game. At the end, the game looks more like a 3rd person shooter and not like a conventional horror game. I think you have it in some places exaggerated with the opponents. While there are some new enemies, right Bossfihgts there but few. The puzzles are rather disappointing because it mostly involves exchanging the power boxes. Why but 5 stars? The level design I liked quite well, the difficulty to normal is is demanding but never unfair. The Synchro is like the first part again well done and Isacc talks, is also of benefit to the atmosphere.
Conclusion: For me, Dead Space 2 is a very good game, in relation to DS1 is Storywise unfortunately weaker.
