Think most of you've heard of this one, so I'll be brief.
Think this is one of those games that are better if you head in blind, but for those of you that prefer a bit of 'why' this review sums things up pretty decently if with a few mild spoilers.
Anyway, one of the more unqiue FPS series still running. Highly recommended if you're into the genera, and haven't played them before.
