Maybe not best graphic engine, may be not real fallout spirit but what a great game !
Very novative aiming, you can cripple one leg with a good old uzi to slow down your ennemy and then finish him with the shootgun in the torso or in the head when he approach... in some case you have to set up tricky and timing strategies to go further.
But really, the most impressive it's how you feel to be in this world, if you're insomniac i expect u a lot of night hours in front of your screen.
Beware : Dowloadable content are not all good, i recommend you only the pitt and point lookout, the rest of them are a bit boring and linear, but there is a very very very good item in operation anchorage.
