Can I buy addons on microsoft and get those addons on my playstation?

Hello Vivaan.

My name is Jonny and I will be assisting you today!

First, thank you so much for contacting us regarding your inquiry/ concern.

I do look forward to resolving this problem together!

No. You need to buy content from the store your game is for, my friend.

No, you'll need to buy it from the PS store. Purchasing from Microsoft/ Xbox will add it to your Xbox account.

What I meant is this

So I have overwatch installed on my ps4

If I buy something from Microsoft which will be an overwatch add on

Will the add on be sent to my playstation?

No one has an answer this is simple, when you buy the addons, the exclusive cars are available to you in the store, without DLC you can not purchase those cars. But even with the addons you buy the cars with XP just like all the cars, you buy them from store

On Windows Phone you can use Microsoft Points for buy addon's on games
