Wow i was Very surprised when i First played this game. As i didn't see the movie i didn't know what to expect. I Strongly believe that this is One of the most original Games out there. What i love is that unlike other games which is based soly on guns as weapons. In this game you have to use true survival instants and survival skills. Things like spears as weapons and catch food to get by certain creatures and to survive certain Situations. Bottom line this game is Amazing and the Sound is Simply Great. Keeps you at the edge of your seat. I enjoyed it so much that even after viewing the ending i kept coming back for more. Great Game, Great sound, Weather you seen the movie or not Play the game as you will enjoy it.
