So it's not horror...so what...what it lacks in horror, makes it up with its unpretentious action sequences ever made.
Dead Space 3 is an exception. Let us remove ourselves from the matrix of the business in which Dead Space 3 operates. What you are presented with is a very intense and well made game. "UNRELENTING" is what I would describe it...almost every turn in the game presents you with gripping action sequences that leave you sitting at the edge of your seat. The horror aspect of Dead Space 3 is still there. However, it has been pushed into the background. What has peen pulled into the forefront is the action that would build up the story into its conclusion...that is if this is the last of the story arc. Indeed, the shift into action is really needed. The game had to bigger, more larger. A lot of characters, especially, the villains had to be up-scaled as well. You can't just leave the characters disappearing into the background of an otherwise, upscaled environment. The necromorphs are also made to look and act even more dangerous in this game. You are presented with an enemy wherein they adopt to your offensive tactic. Shoot the legs and they mutate into a more aggressive second form. Shoot the the arms and you are presented with a multi-target secondary form, though slower, equally as dangerous to the prior. The environment is a living being. The snow moves and shifts, making the targeting of limbs all more difficult but not impossible. The story, all though may seem convoluted, does make sense. It explains the whole necromorph mess.
In conclusion, and which would also serve as a little bit of advice...don't dismiss a game because of what other similar games have done. Dead Space 3 is all worth it. The production values are through the roof...as compared to the other two. People might have gotten tired of the genre but Dead Space 3 does not need to prove itself right. From the beginning of DS 1 to DS3, the developers knew what they were up against...they were up against progression. Progression hindered by gamers' lament over what should be and what should not be. Progression hindered by business. Progression hindered by gamers' expectations or the lack thereof. Come to think of it DS3 had to contend with a lot of things. It's even a surprise that the team behind it would even have the will and energy to make such a game a hit despite what they are up against.
