LEGO Batman 3: Beyond Gotham probably should have been called LEGO Justice League, seeing as it's a deeply enjoyable cooperative romp with loads of DC characters. And Adam West. Who is the best Batman of all time, and helps to distract us from the fact that the gameplay is a step backwards from LEGO Marvel Super Heroes.
What's more important, however, is that you can buy LEGO Batman 3 for £18.31 on PS4.
You'll need to use Rakuten voucher code FEBDEAL10% for the extra saving. Base.com were already the cheapest retailer around at £18.99, but their Rakuten marketplace is cheaper still! Thanks to daveyp1504.
