Quick answer: EA Play Pro members get full access to STAR WARS Zero Company, including cosmetics. EA's Star Wars EA Play page makes that explicit. Do not automatically assume the standard EA Play tier includes the same full-game entitlement.
EA Play Pro status
EA's official page says EA Play Pro members receive full access to Zero Company including cosmetics. At the time checked, EA lists EA Play Pro at $16.99/month or $119.99/year. Membership pricing can change, so use the official page for a purchase decision.
Standard EA Play is not the same promise
The same page lists standard EA Play at $5.99/month or $39.99/year and describes general member benefits such as a 10% discount on EA digital purchases and access to a Play List. The Zero Company statement specifically names EA Play Pro for full access.
That distinction is important. A search result that says "on EA Play" can be misleading if it does not identify the tier. Unless EA adds Zero Company to the standard Play List, this page should not claim that the cheaper tier provides unlimited full-game access.
Should you subscribe or buy?
If you already use EA Play Pro for other premium EA releases, Zero Company adds value to that subscription. If you only want this one game and expect to replay it over a long period, compare the current one-time game price with the months of subscription you expect to keep.
Steam buyers should also know that the Steam version is native and does not require EA App. You do not need an EA Play subscription to buy and play the Steam copy.
Does Pro include Deluxe cosmetics?
EA's wording says full access "including cosmetics." For the precise current entitlement, use the membership page and EA app listing because catalog contents can change over time.
What happens if you cancel Pro?
EA describes Pro access as a membership benefit, so continued access to catalog games depends on maintaining the relevant membership and platform entitlement. If you want permanent ownership independent of a subscription, compare the current purchase price on your preferred storefront. Save-file behavior and future catalog availability should be checked in EA's current membership terms rather than assumed from another game.
