Best part of Dead Space

1. Longer play time (depending on the player and optional missions 20 to 25 hours)
2. interesting new story
3. Not only interact in a spaceship in the corridors, but also on an ice planet
4. Waffenmodis are interesting and variable.
5. interesting new, bizarre enemies and soldiers as opponents

negative I see:
Only 2 weapon slots

What should also be noted:
Here is an even greater stress factor than in the old parts, because from about 75% of the game is played almost exclusively under time pressure. Is a matter of taste, I personally a bit too stressful
