This is essentially Half-Life 2, but even better in my opinion! The game is divided into different distinct sections, and all of them have a different game feel to them. While there are no vehicle sections, that is more than made up for by the flow that this game had. I completed this game in one single sitting without taking any breaks. A game that lets you do that is incredible in my books. The final battle against a Strider is also one of the best fights in the Half-Life series. Simply amazing!
