If you're a PC games player and you don't know about Humble Bundle then you've been missing out. This site brings great deals on a continual basis, letting you pay what you want for a selection of top titles and also adding to the lineup as the sale continues. It's a great way to stock up on Steam games that you'll never have time in your entire life to play, which is a good and bad thing we suppose.
In 2015 they launched a new initiative with a monthly subscription service - you paid $12 a month and got a secret selection of titles. Now they're going one better by offering a sneak peak every month and the first title is most impressive indeed, Alien Isolation.
This game will technically be part of the February 2016 pack but if you pay the 12 quid now you can unlock the game immediately. So you get to wander around and try not to die at the hands of a xenomorph, warm in the knowledge that you'll be getting a handful of extra games in a few short weeks. That's a pretty great deal, especially for anyone who was curious about the game but didn't manage to pick it up yet.
And while this Humble pack is technically a subscription service, you can easily just sign up when it's a game you want and unsubscribe afterwards. You get to keep all your games (unlike PlayStation Plus) and you can dive back in when you feel so inclined.
