Description
Like it's name the Health Gauge is a Gauge that represents the life meter of the Vehicle users. The Health Gauge main appearance is a grey oblong with blue oblong inside it that represents the life meter and the replacement of the rings. When it is full the Health Gauge's color is blue, but if the player gets a hit then the color of the gauge will be yellow and then red if the player takes more hits  if their HP gauge is completely depleted then the player will lose his life. The Health Gauge can be refilled by rings or by a Health Item. In Eggman's case the Hp Gauge can be upgraded by having the Protection Armor and then the Health Item will resist more and it's color will be dark blue.
