Hijack eco vehicle is a mission in Jak 3. Ashelin Praxis gave Jak a call with the communicator saying she got word of a KG Death Bots eco shipment in the Industrial Section and wanted him to steal the vehicle for the war effort.
The PlayStation 3 and Vita versions of this mission are related to a trophy named "Hi Jak!", completing this mission will reward you with a bronze trophy.
As soon as you steal the vehicle a nearby missile launcher will launch several missiles who will chase you through the Industrial Section and the Port district. This vehicle has an excellent sensitivity when making turns, as you can't slow down or the missiles will hit you. Keep speeding on until you reach the Port, where several decoy beacons are placed throughout the water. Shoot these from a distance with the Beam Reflexor and then fly close by to let a missile veer off and destroy it.
With one missile remaining head for the Naughty Ottsel to end this mission with a cutscene.
