Thats not what’s going on here. CoD has for the past few releases run an open beta for 2 to 3 weeks, a month or two ahead of release. Buying this package lets you into that 2-3 week beta a week early, letting you get 3-4 weeks of playtime. You can still get into this beta for completely free, just wait a week and don’t buy the game.
Not trying to defend Activision here, cause I still think CoD is a shadow of its former self and these “betas” are nothing more than a demo, but people seem to have the wrong idea about how Activision runs them.
