It's not often we feature MS-DOS games, unless of course it's a glorious classic released on GOG, but today's announcement is something special. As we've been told by a member on our MS-DOS Gaming Facebook group, that Jani Nykänen has released a new game for MS-DOS called ' Plutonium Caverns '. This game which is also playable online, is a 2D top down puzzle game in which you need to collect all the diamonds to move on to the next level.
