Nintendo has announced the three games being added to the NES library available as part of Nintendo Switch Online subscriptions, all of which will be available on April 10.
Super Mario Bros.: The Lost Levels, Punch-Out!! Featuring Mr. Dream, and Star Soldier are the three titles Nintendo will add in April to a collection that already includes Super Mario Bros. 3, The Legend of Zelda, and more.
Super Mario Bros.: The Lost Levels was originally released in Japan as Super Mario Bros. 2 and prominently came to North America as The Lost Levels in the Super Mario All-Stars Collection.
Punch-Out!! will see players take on the role of Little Mac, duking it out with the heavyweights of the World Video Boxing Association circuit, starting out with Glass Joe.
