Destroy Prototype Facility is the sixteenth GDI mission in the Tiberian Sun campaign. It takes place in south-eastern Europe during the Second Tiberium War, where Banshees are being developed. This mission offers two choices.

EVA Briefing

One of two possible locations of the Prototype Manufacturing Facility. Use the mutants to locate the position of the production facility. The mutants must remain undetected. If Nod suspects enemy forces in the area, they will cloak the facility and deploy troops to destroy them. If the mutants can hide from the Nod troops for a short period, the base will assume the area is clear and uncloak. Once we record the location of the base. GDI Dropships will arrive with reinforcements.

  • Objective One: Using mutants you must locate the Prototype Manufacturing Facility.
  • Objective Two: Once the facility is located reinforcements will be sent in to help construct a base. You are to destroy the Manufacturing Facility at this time.


After the destruction of the chemical missile plant, Tratos confessed to McNeil that he helped Kane translate the Tacitus, thus giving Kane the knowledge how to transform Earth into a Tiberium-based life. McNeil tries to tell General Solomon of Kane's plan but having been surprised by Nod's prototype Banshees during GDI's attack on the plant, Solomon ordered the complete destruction of the prototype facility. EVA pinpointed the location and noted that Nod is using stealth generators to cloak the facility. Umagon volunteers to lead the mutants party to find the facility using stealth before McNeil sent in a force to wipe it out.

The battle

Regardless on the choice of location, the first party always come with full Forgotten service such as Ghoststalker, Umagon, and mutant hijacker. Roaming the field, they might encounter a Nod outpost and nearby Banshee flying for target practice. In one selection of the mission, the mutant hijacker can take control of an old Mammoth Mk. I that was being targeted by banshees for field testing. Advancing further, the party discovers the base. But due to detection, the base stealths itself. The mutant force withdraws shortly after (excluding hijacker if he commandered anything).

The counter however does not stop the GDI commander from deploying a sizable force in the area. This force includes the prototype Mammoth Mk. II. Nod, as always, sends in welcoming envoys backed by Devil's Tongues and Attack cycles. These can be effectively countered by the trusty Titan, while GDI airplanes secure Nod 's base perimeter and mop up opposition as they can. Nod also light up the night with their newly acquired toys. In the end, a friendly visit ends the day completely. The "last visit" is well documented and presented to GDI high command as a proof of MK. II viability and destructive power.


The facility mass-producing the Banshees was wiped out thanks to GDI's own prototype, the Mammoth Mk. II. However Umagon was captured by Nod and brought before Kane himself.




If the player captures the Nod Construction Yard and techs up, the Temple of Nod is available, as are the production options that come with it, including the Mutant Hijacker. This option makes this misssion the only time in either Tiberian Sun or Firestorm where a player can control more than one of the same commando unit.
