Information about how to find the Forgotten Prototype (AKA the “Rocket Car”) in Saints Row, including the locations of all the Lost Wheel Discoveries that yield one of the Forgotten Prototype components.
How to Find and Assemble the Forgotten Prototype in Saints Row
The Forgotten Prototype is a unique vehicle in Saints Row, which can be obtained by finding all its five components scattered throughout the desert. Once all the components are obtained, this vehicle will automatically be assembled and you’ll be able to drive and customize it by visiting your garage, just like any other vehicle. You can find the components by looting Lost Wheels Discoveries which, in this case of this vehicle, are all found in the Badlands North region of the map.
Consult the map below to find all five Lost Wheels you’ll need to loot to unlock this vehicle.
Shark-Fin Winglets: Along the southeastern end of the Badlands North region, near a campsite off a dirt road. This is the southernmost Lost Wheel in this region.
Rocket Engine (Left): You can find this Lost Wheel along the eastern end of the Badlands North region, on a hill overlooking (southwest of) some train tracks. It is the second southernmost Lost Wheel in the area.
Rocket Engine (Right): Located next to the paved road that bisects the Badlands North region, near a bridge running over some train track. This Lost Wheel is the middle of the five on the map (above).
Aerospace-Grade Aluminum Body: You can find this Lost Wheel along a dirt road leading up to the abandoned mine found along the northwestern end of the Badlands North region. It is the northwesternmost of the five Lost Wheels on the map (above).
Ultra Heat-Resistant Tires: You can find this Lost Wheel along the northern end of the train tracks that run north/south through the Badlands North, just in front of an elevated rail bridge. It is the northernmost of the five Lost Wheels on the map (above), sandwiched between the House Phoenix Dragon (west) and the Watering Hole (east) Photo Hunts.
Once assembled, the Forgotten Prototype will be placed in your garage as a [Vindicator] vehicle. It has the Nitrous upgrade unlocked by default, and even without it, the Forgotten Prototype is a fast vehicle with moderate Performance and Durability stats, and good Off-Road capabilities. Its off-roading capabilities can be further improved by installing an Off-Road Kit. and overall it’s a sporty, fast, space-age vehicle that leaves little to be desired, especially once upgraded. You can unlock the “Infinite Boost” Signature Ability for it by performing three full Nitrous burns.
