The makers of popular XCOM mod The Long War (you can read Chris' take on that here) have formed a development studio. It's named, pretty cannily, Long War Studios, and its first game is a strategy title where you have to defend Earth during an alien invasion.
It's not called YCOM, ZCOM, or even XCO.UK; Long War's game is titled Terra Invicta, and it'll be more of a "grand strategy" than Firaxis' smaller-scale operation. Here is everything we know about it so far (there are no images yet), before Terra Invicta heads to Kickstarter sometime in the future:
"Terra Invicta is a grand strategy game in which the player leads the defense of Earth during an alien invasion.
"An alien force has arrived in the far reaches of Solar System and begun probing Earth's defenses and building an invasion fleet. The player must assemble a council of scientists, politicians, military leaders and operatives who can unite Earth's squabbling nations with the ultimate goal of taking the fight to the aliens in the high ground of outer space."
It sounds like a more strategic, less fighty XCOM, and if it's even slightly like Europa Universalis but with space aliens, I think we would all be happy with that, right? (Thanks, NeoGAF.)
