The word "burnout" means the reduction of a fuel or substance to nothing through use or combustion. Its name is a reference to the Burnout series of arcade racing games, where there is a reward for using up all of the in-game "boost" in one go.
To earn it, spend a lot of sun at the end to get it, as well as avoid picking up sun as much as possible. However, sometimes the totals do not work and you cannot get it to have no sun at the end. If this happens, you may think about using Plant Perk and ZombiFreeze, as they are cheap and can be used for an unlilmited amount of times.
- Burnout and Solar Saver were impossible to get at the same time.
