In 2001 Bandai announced Mobilesuit Gundam MSPlatoon.com for WonderSwan Color. However the game concept, known during production as “the Net Gundam“, first concept was in 1997 when developers at Bandai started to think to create a Gundam game designed to work over the Internet. MSPlatoon.com was a strategy game that allowed gamers to play as a soldier for the Republic of Zion or the Earth Federation and engage fights in operation plans announced every week by server-side so to battle with other humans online. Over the time you could even become a leader of your chosen side.
The online component was guaranteed through the WonderGate, an add on that allowed the WonderSwan to access to NTT Docomo network, or through a special cartridge to connect with a PC (see image below). This interesting title, the first multiplayer online game for a dedicated handheld system, was planned to be released in autumn of the same year but seems the concept was far too ambitious so Bandai quietly cancelled the project.
