The choice is made through interaction with Silver Dragon, a local cultist who vandalized WC property and is trapped in the basement of the WorldCorp building. Choosing to rescue him will help PDX, while choosing to kill him will help WC. If the player chooses to work with PDX, Trestkon is sent to spy on their primary suspect for the abduction, WorldCorp. This puts them on to the existence of an old device that may be able to lead them to Deus Diablo, buried in the ruins of the city that Forum City was literally built on top of, Deus Ex Incarnate. After dealing with an incident of sabotage by WorldCorp, Trestkon delves into the ruins and retrieves the device, known as the "Firestaff". Trestkon then returns to Forum City where he must promptly deal with an ambush by WorldCorp mercenaries who have attacked the city in a desperate stalling move. Back at PDX headquarters, the Firestaff reveals that Deus Diablo is located on a previously unknown space station orbiting Forumplanet. Trestkon is sent to rescue the only independent helicopter pilot in the city from the clutches of a terrorist organisation (whom he may either annihilate or forge a truce with) so he can get to Aunt Betty Industries, a clothing factory outside the City which is a front for a space research facility. There, Trestkon secures a shuttle that takes him to the space station. If the player chooses to work for WorldCorp, he is immediately told about the Firestaff, its purpose, and its location. Unfortunately DXI is closed to the public, including WorldCorp agents, so in order to gain access, Trestkon must acquire the highly guarded admin password for the city. Following a failed blackmail attempt and a dangerous loyalty test, Trestkon finally manages to steal the password from PDX's high-security server complex and goes into DXI to retrieve the Firestaff. In this storyline too, Trestkon emerges into an ambush, but this time set up by PDX. When the Firestaff reveals Deus Diablo's orbital location, he is sent to steal a helicopter and interrogate its pilot to obtain the codes to its navigation system. As a final obstacle before he can go to Aunt Betty Industries for their space shuttle, Trestkon is forced to infiltrate an air-control tower to lift an electronic lockdown detaining the helicopter. In either storyline, when Trestkon reaches the space station, he is faced with the final decision of what faction to support.
