For the next 48 hours, Humble Bundle is giving away free copies of The Bureau: XCOM Declassified. Picking up The Bureau also gets you a 10% discount on the Humble monthly subscription.
The game is provided via Steam key for Windows and Mac. For key redemption, a free Steam account is required to redeem the code. Naturally.
For those who missed the game when it initially released, the official description is below.
The year is 1962 and the Cold War has the nation gripped by fear. A top-secret government unit called The Bureau begins investigating a series of mysterious attacks by an enemy more powerful than communism. As agent Carter, call the shots, pull the trigger and lead your squad in a gripping third-person tactical shooter set within a covert war to protect humanity from an otherworldly enemy.
You can pick up The Bureau for free here.
Humble has some other sales going today, though not as impressive as those from last weekend.
