The clock is ticking. In a matter of days, the alien Pharos will be executed by H.A.L.O. for his crimes against Earth. It's up to Equilibrium agent Parminder Patel to find out what she can about the great warrior's past, and learn more about the imminent Borealis threat, before it's too late. Lucky for her, she's not alone; another player secretly stalks the H.A.L.O. facility. Someone who has come from another world entirely!
