As Nintendo continues to make its classic NES content available to subscribers of Nintendo Switch Online, we have come to expect a few new surprises along with the previously announced lineup of games we know we will be getting on the service. The last time, it was a special variant of the NES Legend of Zelda game. This time around, it’s a special version of the classic puzzle game Dr. Mario, as well as of the original Metroid.

But first, let’s look at the three games that were already announced for this month for subscribers, and which are now available—the NES Ninja Gaiden, Wario’s Woods, and Adventures of Lolo. All three can be accessed from the NES app, as can be Dr. Mario and Metroid’s special versions. The former starts you at Level 20 at Hi Speed, while the later gives you all of Samus’ abilities, and puts you right before the Ridley fight.

Those are some nice surprises, and a nice new way to approach these otherwise dated classic games that have now been played so many times by a lot of players that they have lost their ability to surprise.
