On Twitter, Kojima has revealed a black version of the Ludens action figure by Sentinel. It will be available for purchase during the Shanghai Wonder Festival, taking place next month. Here are some pictures taken by Kojima comparing this new version to the white Ludens released earlier.
The white version contains two types of visor and lights than can light up inside the helmet. Presumably, the black version will feature the same details, but Kojima did not elaborate on this. The figure is about 30 cm (~12″) tall.
