HIGHLY recommended - especially if you're a fan of the Alien films in any way shape or form!
Obviously, it's not a "shooter", but a very well rendered and tense "sci-fi horror".
I waited for a cheap secondhand copy for the Xbox 360 to crop up on eBay, but they always seemed to go for silly money - I picked up a brand new (and therefore including valid DLC codes) "Ripley edition" from GAME for £22. Expensive compared to my usual shopping habits, but well worth it in my opinion
When men meet foes in fight, better is stout heart than sharp sword.
