Extinction is a game with potential which was ruined by bad pricing and bad gameplay/story decisions. It could've been a better game if it had a cheaper price with more features. However, in its state, it only fails to be an impressive game. If you are a huge fan of action games, and if you don't mind repetitive gameplay with weak storyline, but with good graphics and sound effects, you can go ahead and try it. Otherwise, I'd recommend waiting for an update or a discount.
