As MrYd said there both supposedly on the disc for Xbox, apparently from what i read of a statement on
gamespot via twitter it's hard to have 2 multiplayer games on one disc on PS4 without needing to make a separate menu, then R1MJAW said last night that apparently in Germany i think it was both games are on the PS4 disc, i went the download route it is quite hard to spot a lot of the spit and polish but if you do see images side by side it's clearly there lighting foliage and so on.
