The Internet Archive launched a campaign to preserve classic console games a little over a year ago. In that short amount of time, the non-profit digital library has amassed quite a collection of titles which are playable right in your browser.

The latest addition to the library comes in the form of nearly 2,400 classic MS-DOS games and like before, each can be played free of charge using their browser-based emulator. Given the fact that it’s still in beta means you’re likely to encounter some bugs and other quirky behavior but that’s alright because again, they’re all free to play.

Some of the more popular titles that you might recognize include the original Prince of Persia, Wolfenstein 3D, Commander Keen, The Incredible Machine, Street Fighter II, The Oregon Trail and Wasteland. Oh, and there’s even Mario Teaches Typing should you need to freshen up on your keyboard skills.

As was the case with the previous batch of games, the MS-DOS titles come sans instruction manual so it’ll be up to you to figure out exactly how to play them.

While probably not a big deal for the millennial generation, many of our readers likely grew up playing some of these titles and will no doubt be treated to a trip down memory lane. For the Internet Arcade, it’s another step forward as they’ve already enjoyed more than five million visitors since inception.
