Builds really well off the first game. A much bigger scope, with the bombast and scale of a Halo game. Huge sieges, multiple vehicle sections and wild chases. There's a wry sense of humour to some of the bigger bosses, new enemies and mechanics. The action feels a little less intimate, but more thrilling and fast paced than the first game. None of the spectacle overwhelms the game or makes it too unserious though. There's still a sense of the cost of war, and the end ties all this together well.
