Despite the game already being out, Metal Gear Solid V: The Phantom Pain will be making an appearance at Tokyo Game Show 2015, coming up later this month. It will be present in playable form, as well as with a trailer.
Konami has opened its official website for TGS 2015, which you can find here. The Japanese site also mentions FOB and Metal Gear Online.
It seems from the confirmed lineup that Konami has little else to show, the only other console title aside from MGSV is PES 2016.
There will also be a series of stage events, but a schedule hasn’t been announced yet.
Tokyo Game Show 2015 takes place September 17th – September 19th.
