StarCraft II mod takes 6v6 combat into space
A custom made StarCraft II map going by the name of Star Battle has added 6v6 space combat to the RTS. That's combat in space, not on planets.
The whole thing's inspired by DotA, and allows players to take command of one of four unique super-ships.
It's a Terran versus Protoss affair.
There's a video below of TotalBiscuit - of I Suck at StarCraft II fame - talking through a game, which he claims is now the most popular custom map on the EU servers.
It's since been released on the US servers.
Have a watch. Full details here.
