GOG’s winter sale is still going on, and new games are being added to its lineup on a daily basis. Beyond new games simply getting deep discounts, we’re now seeing new games added to the service as a whole too. Bioshock 1 and Bioshock 2 joined GOG for the first time, making this the first time that either game has been available DRM-free. Both games will have a regular price of $19.99 – making them $40 for the pair. However, if you buy them during the winter sale, you can get them for $4.99 apiece or a shade under $10 for both – making this an outstanding value until the sale ends on January 1. If you have never played either game, this is a fantastic way to do so and the only way to enjoy them without any kind of DRM attached to them.
