Halo Wars 2 will have all of the key elements of a good real time strategy game, but it will also have some elements that could have only come from completely out of the box thinking at the Halo Wars headquarters.

It has been revealed that a 'mysterious mode' in Halo Wars 2 will offer gameplay that's unlike any RTS experience we have seen before.

Unfortunately we do not have any information about the mysterious Halo Wars 2 mode, besides a small tease from 343 Industries Studio Head Dan Ayoub, who said, "One of the modes, which I can only tease for the time being, is actually a completely new way to play a RTS. It really takes standard RTS gameplay and turns it on its head. And that's a mode that can be played in a shorter time frame as well, like five, six, seven minutes."

It's hard to say whether the new mode will truly turn RTS on it's head, or whether Ayoub's statement was a little overhyped. It seems that they have designed some kind of quick match mode that will allow players to get in and out of the action as quickly as possible. Besides that, it's very hard to know exactly what this new game mode will entail.

Perhaps the game mode could be limited time-wise due to some kind of flood invasion or activation of some kind of forerunner artefact. Alternatively, Halo Wars 2 could have simply taken the usual RTS game formula and sped up everything from unit recruitment to unit travel time.

Whatever the 'mysterious mode' is, we'll definitely find out more about it soon.
