On top of access to online play and a library of classic NES games, one of the perks of subscribing to the upcoming Nintendo Switch Online service is "special offers" available exclusively for members. So far, Nintendo hasn't revealed many details about what these offers will entail, but we've gotten a look at the first ones that will be available when the service launches.

First, Nintendo Switch Online subscribers will be able to purchase the newly revealed NES-style Joy-Con controllers. You'll only be able to order these if you have a Switch Online membership. Each set costs $60 and comes with two controllers shaped like classic NES gamepads, which can be used to play the aforementioned NES game library included in the service. The controllers can be charged by slotting them into the sides of the Switch, just as regular Joy-Cons, but they can't be used in handheld mode.
