The game’s played in the corridors of power in Westminister and Washington. It’s played in alleyways in Bangkok and desolate hillsides in Afghanistan. It’s played in the skies of distant alien worlds, where terrible things slumber behind the wall of pain. The game’s played with bullets and with secrets, and they’re both equally deadly.

Our opponents in this game are cultists and monsters. Some of them are deluded pawns. Others know what they’ll unleash with their next move. If we lose the game, we lose everything.
