Beta - Something up with the store?

It's a bonus for being a member with gamestop's power up reward, in the uk game, ms store probabaly had something but its not an open beta it's a demo.

The beta has to be searched in the store under avengers beta not marvel avengers beta because it will not show up

has any one got the beta as it is up on PlayStation store now

It is as indicated by the name you can not access the store from a beta version if you want to buy something I recommend you install the official version so you can buy products in the store

I'm not sure if it will still be available to play as the beta is only up until Sept 4 but you can try. Head to the xbox store and search for Private Beta to download it.
