Kronstadt Octane Afterburner occurs only in Miami (The Finish Line) mission and is one of the story-related items in Hitman 2. You can use it to complete two challenges - to kill Robert and Sierra Knox.
- External Combustion Engine - add the afterburner to the engine fixed by Robert during the event;
- Hot Shot - add the afterburner to chili on the upper floor over the garages and participate in the drinking game with Sierra (as Moses Lee);
- Additionally: Kronstadt Octane Afterburner - works like a grenade - throw it to make it explode.
You can find it at Kronstadt building, in its north part, in the garage near the Podium. It lies in the showcase from the west side. It appears here only when you're not completing the Mastery level of this assignment.
Moreover, it can be found in nearly any garage. You are not welcome there unless you wear either the mechanic outfit or the race outfit (from the same team whose garage you wish to enter).
