Last week, 2K teased us with a cryptic website: AdventFuture.org. On it, a supposedly utopian near-future government called the Advent Administration offered a better life for citizens through genetic enhancement, while hackers subversively replaced text and images revealing that Advent isn’t as benevolent as it seems.

Today, IGN First officially announces that the game 2K hinted at is in fact Firaxis Games’ XCOM 2 XCOM: Enemy Unknown and a continuation of the now 20-year-old legendary turn-based tactical squad combat series, which will be available exclusively on PC this November. Watch the debut trailer above for a glimpse into a future where the aliens are in control of the Earth, and XCOM has gone underground to fight to overthrow their Advent government. This new guerrilla force will face more powerful enemies in unpredictable combat scenarios as they fight to turn the tables on a technologically superior enemy.
