GOG.com has been the go-to resource for DRM-free games for years, and today, they announced that 15 Neo-Geo classics are available to purchase on their site. The Metal Slug bundle gets you Metal Slug, Metal Slug 2, Metal Slug 3, and Metal Slug X for a mere $5.96. The fighting classics bundle gets you Fatal Fury Special, Samurai Shodown 2, Samurai Shodown V Special, King of Fighters 2000, King of Fighters 2002, and The Last Blade for $8.94. Finally, the arcade games bundle gets you Blazing Star, Baseball Stars 2, Shock Troopers, Twinkle Star Sprites, and King of the Monsters for $7.45. These bundles are available for one week – after that time, the games will be split up and sold for $5.99 apiece – so this is a heck of a savings overall.
