There was no doubt that Metal Gear Online would get a beta version, a version that helps developer find bugs and lets players get a more detailed feel of what they're getting.

However, Konami initially announced the beta version only for the Japanese and U.S. market, but it seems that will not be the case. European fans will also get a chance to play the beta, but it will not be compatible to the Japanese version, meaning that during testing, E.U. gamers won't get a chance to test their skills against their Japanese brothers in arms. 

Further information was unavailable, so we will report as soon as we know more.
