This game is truly awesome and it does really realy on tactics when your trying to hide or sneak!
This is a new kind of game that you cant find any were else!
It combines Real Time with Turn Based like lets give example.
There is a Raider down the hall and you are in front of the hall,
you are not yet in the Raiders line of sight BUT,
you can also set some traps and get ready for the Raider to come for you and try to hid because he has long range weapons!
So you have the choice of fighting the Raider down the hall and risking your life and his, or, you let him come to you after setting some traps and risking your life but making sure the Raider is dead!
