game is in open beta this weekend on pc, ps4, and xbone. its live if you had the previous beta, otherwise you can play tomorrow (preload today). on ps4 i just went into the store, went to preorders, rainbow six, and under Other on the left side there was a free beta download link. almost 9 gig client download.
same on PC under uplay, but the game starts up in 3D mode for some reason for me lol
if you were thinking about buying i'd play the beta, i think its a shit game
