This is a pure shooter game ;)
Play the hero Gordon Freeman, while assisted in every technical issue of his 'girlfriend' Alyx. She is a real honey-babe, with intelligence ;)
The game continues where we left the heroes in the previous game. Our mission is to find the route, far away from the collapsing tower, before all go to hell.
PROS:
A type of lovestory, where Gordon and Alyx survive together, despite the army that will separate them with force.
The graphic is like in a movie. I often stop to study the environment, like in real.
A rich variety of weapons. Here the gravity gun must be used in every specter of the game.
CONS:
This is 'only' an episode. Rounded the game after some hours.
