Is it possible to play Forza Horizon 3 (xbox one) together on an xbox with 2 pushers?
As far as I remember the Horizon parts have no splitscreen, the 4 does not have any.
Incidentally, that would be technically feasible only with extreme drawbacks, which would like to take into account in such graphical showpiece titles.
The motorsport series, however, has a split screen. For the rest, this is also on the pack or description of the game.
And while I'm at it. The pushers call themselves controllers. 😉
