Big things are going on in Japan, mainly, the announcement that the closed beta for Metal Gear Online will happen shortly. Three thousand carefully selected Japanese beta testers will put the game through its paces until it's ready for open beta, and finally, retail. Metal Gear Online is a PS3 title.
According to GameSpot:
The game will be a kind of hide-and-seek for up to 16 players at a time, and is called a "strategic multiplayer experience." It will feature the SOP system which allows players to keep track of their teammates via nanomachines injected into their bloodstream. The nanomachines allow them to see where the rest of their team are, their condition, which way they are aiming, and their range of sight. Enemy soldiers can also be injected with nanomachines, which will enable the other team to then keep track of their movements.
Metal Gear Online will also feature playable characters and environments from Metal Gear Solid 4: Guns of the Patriots, and is currently slated as a PlayStation 3 exclusive.
