Following its inclusion in EA's successful The Orange Box, Valve's dimension-bending shooter Portal has become somewhat of a cult classic – and now developer Valve has said that there's plenty more to come from the franchise.
Speaking to Eurogamer, Valve's Doug Lombardi said of a possible add-on or sequel: "There'll be more Portal, for sure. But the details of that, to be honest, we're still working out.
"The only smart thing we did for Portal was to hire those seven kids and give them the support they needed to make the game."
There's still no word on when gamers might be able to expect more Portal to hit the shelves.
