Bayonetta 2 is released this week for Wii U, and Nintendo are offering some incentives to buy the game - plus the port of the original - digitally.
You can buy the sequel for £39.99 from Nintendo's eShop store. Do so and you can download the original (RRP: £24.99) for £9.99 as a follow up download. It works in reverse as well - buy the original and you can purchase the sequel for a reduced price of £24.99.
It works out the same price regardless, and you can actually buy the retail Special Edition double-pack for five quid less anyway, but if you'd rather avoid swopping discs...
We reviewed Bayonetta 2 last week, and called it "one of the most compelling reasons to pick up a Wii U".
