Still missing a bit on exit from Final Fantasy XV Windows Edition, but apparently all players who choose to purchase a copy of the game on Windows Store can play co-op with Xbox One Edition owners. Just below, the screen that would show it.
But be careful: it appears that the function is available only if you buy a copy of the game through the store Windows, saw that on Steam thecrossplay feature doesn’t seem to be available.
You have already read in any case that a glitch in the benchmark lets you control Noctis?
If you want to know more about the game, please refer to our inevitable video review of Final Fantasy XV, only ever SpazioGames pages!
