My review.
First of all , I gotta say that the game is one of the best looking shooters out now :) While this is one of the games sellings points it also limits the numbers of people that will be able to fully enjoy the game.
The system requirements of the game are extremely high and many people will have to buy a new high-end pc to enjoy the game and all the impressive technology that powers it.
But don't worry , I think the game is absolutely worth upgrading or buying a new pc. The gameplay is outstanding, shooting the guns in the game feel appropriately devestating and the sci-fi elements that appear later in the game are a welcome addition.
