Nintendo has added to Switch Online’s collection of NES games by releasing a few expected new titles and one rather surprising one.

Starting today, Nintendo Switch Online subscribers will be able to access previously announced NES titles Metroid, Mighty Bomb Jack, and Twinbee. Metroid is the clear headline title of the three. This classic NES game changed the way that we looked at the design of action/adventure games and pretty much created the idea of atmospheric gaming in the process. Sure, Super Metroid is superior in just about every way, but Metroid holds up shockingly well.

Mighty Bomb Jack and Twinbee are a bit more obscure. Actually, Mighty Bomb Jack received some fairly negative reviews upon its release, and it hasn’t exactly aged gracefully in the years since its debut. Twinbee, a vertical shooter made by Konami, is about as well-remembered/worth playing.

Speaking of Konami, Nintendo decided to include a surprise game in this Nintendo Switch Online update; a special edition of the classic NES shooter, Gradius.
