The Lost Vikings and Rock N' Roll Racing are two of Blizzard's most classic classics, published in 1992 and 1993 respectively, when Blizzard Entertainment was still known as Silicon and Synapse. If, as I did, you missed out on them when they were current, now is your chance to experience all their pixelated glory. Unfortunately, they are only available for Windows operating system, so if you're a Mac user, you may be out of luck.
To find the new downloads, click on the "Games & Codes" option in your Battle.net account, then click "Download Game Clients" from the drop-down menu. The Lost Vikings and Rock N' Roll Racing can be found under the "Classic Games" section.
