GOG recently added 27 classic PC games to its ever-expanding "Preservation Program".

GOG's "Game Protection Program" was announced last November to ensure that classic games can still be played permanently on modern PCs even after developers stop supporting them.

The latest games to be added to the program include Silent Hill 4: Room of Secret, Extreme Panic: Platinum Edition and three Tomb Raider games.

While the company's spring promotion is still in progress, all newly added games (and most existing ones) enjoy discounts.
