This game teaches you that tube can be exciting if it is done properly since.
This is perhaps one of the few drawbacks - there is no choice, but only one way to there to master - and this has provided in sich- to play in Survival mode.
However, the zones are designed to limit this tube so well adapted to the environment that they feel neither illogical nor disturbing.
Also you could make something fun-opponents. Otherwise the principle is where the beginning is almost the same to the end.
Finally, I would still the strange behavior of the light "flashlight" fault - although an old oil lamp used in the game instead. The light is oddly (I do not know if this is intentional) scattered in a very low level forward, for the most part left, right and rear. Especially the area the one actually wants to illuminate remains extremely dark. With the lamp off can be seen on the other hand often nothing at all.
Now for the positives.
Despite almost cinematic graphics it creates the game in this stay afloat.
The 16 sections available to create are visually quite varied designed so that in the 21 hours. Time that I have used for example to complete boredom arose.
There is a good balance between hide / attacks from ambush, open fight and sometimes run away.
The bosses are designed very intresting, and is groping in the dark a long time what the ever going on.
The film sequences reveal exactly as much as is necessary to ensure that the voltage is maintained until the end.
In conclusion, I would say a good mix in the way between Silent Hill and Dead Space.
