Batman: Arkham Insurgency - 10 Best Rumours That Must Come True

4. Play As Batman & Robin

The substantial leak was quick to point out that sadly, we won't be able to play as Dick Grayson's Robin out in the open world of Gotham, but for the first time in the series, there will be an entirely separate skill tree featuring a number of abilities and upgrades, meaning he plays a significant part in the story.

Part of this upgrade menu also involves an entire 'branch' of unlockables dedicated to the tag-team moves we saw in Arkham Knight, assumedly meaning we'll be spending a lot of time alternating between Batman and Robin, before having greater control on how the two work together.

If this points to the same sort of structure as Arkham Asylum - large open areas but not an open-world structure per se - it could be a solid balance of linear, memorable levels where you have a choice of who to play, joined by expanses where you're otherwise exploring as Batman.

Perfect.
