Was very pleased that this arrived this morning, a whole day ahead of release!

Single player campaign is really intense, with a few moments that are sure to be in the papers - pretty harrowing stuff. They've put a nice handy "you can skip this stuff if it bothers you" warning on the start though.
Great involving twisting storyline. Again quite short but high-quality.

They've managed to make the best multiplayer game even better. So many things to collect and do, and bloody hundreds of setup combinations. The maps are pretty sweet too, and not entirely restricted to areas found in the single player campaign.

There's a co-op special ops mode too that I haven't tried yet but am intrigued.

Just stopped playing after 9 hours solid. My hands are aching and I'm all twitchy. Epic game.
