Today Kojima posted this picture on his Twitter, accompanied by the word ‘checking’. It consists of the text ‘Metal Gear Solid’ decorated with a bunch of Snakes from different games throughout the series.
What this is exactly remains unclear, since Kojima didn’t provide anymore information. There are rumors going on of an incoming Metal Gear Solid Legacy Collection for PlayStation 3. This title has been listed by a Korean rating board that has proven accurate before. This could have something to do with that, but it’s all speculation. Maybe the logo is just for a new merchandise item. It could be a design for a t-shirt or a poster, for example. In any case, it looks interesting.
