Genuinely think they found something totally new here with the objective capture/deliver gametypes and the destruction engine. The latter really makes things just the right amount of predictable, with the play space shifting around players' actions. There's a very good and satisfying to learn skill ceiling involved with figuring out how to best use that destruction to your advantage. At first it's a pretty spectacle and a fun toy, but soon it opens up into a way to take control of the environment. An enemy team is capturing an objective. Do you enter from their floor? Break through the ceiling and drop in from above? Maybe you destroy the floor beneath them, dropping the objective to the next floor down where you've already set up to take advantage of its new placement?

It's a hell of a lot of fun.
