Evolve can be fantastic fun, but it's also worryingly light on content for a full-priced AAA game. So if you're in the market for 4 new hunters (when they're released) and 3 exclusive Magma monster skins, you might be well suited by this cheap Season Pass deal, especially since it costs £19.99 at full whack!

I mentioned that I have concerns about Evolve's value. You can read more in our Evolve launch impressions, and you might want to hold out for our full review before taking the plunge. We'd also suggest waiting to see what the new content involves before putting money down -- but it is your money at the end of the day.
