The shield system refers to a system of defensive racing weapons featured in Jak X: Combat Racing, comprising the damage shield and its dark eco variant the deadly shield. When activated, an impenetrable force field will surround your race car, protecting you from even the strongest weapons such as the Stellar Nova or Super Peace Maker (in fact, it is the only weapon capable of protecting you from these weapons). The only thing it cannot protect you from is falling to your death, drowning in water, or trespassing game bounds.
