Mission 5: A Friendly Foe As you approach Mars, you are attacked by three fallen ships. Sustaining heavy damage, you crash land your ship on Mars near Ark Fall. Desperate for a way to fix your ship, you approach the crash site. You see a huge crater with nothing inside. As you approach it, your ghost bumps into something. He then realizes what it is, and tells you that the ship is still at the site with a cloaking device equipped. Your ghost then begins to scan the ship to locate an opening, where you are soon attacked by an unknown, humanoid species. After a vicious battle with seemingly immortal, fast creatures, a lone Fallen emerges from the hatch and kills the dark figures by disintegrating them with the ship's engine. You stand in shock and notice the Fallen, who says "ME. SMITH. SIRIUS." with a toothy grin. A man's voice is heard within the ship, and the Fallen scurries back in, leaving the hatch open. You enter the ship and see a man. The man dressed as a Titan stares for a while, then introduces himself as a mere Titan with no purpose and the Fallen as Sirius. He then threatens you that, should you kill the smiling Fallen, you will receive multiple shotgun shells down your throat. He then gives you a night's rest in the ship. (The player can no longer leave Mars until they complete the next missions.)
