Shield

A player's shield is a percentage indicating how much damage they can sustain before their health being decreased. It is displayed in green on the HUD. When the player's shield is 0, any further damage will be dealt to the player's health. It is possible for a player's shield to be over 100, by picking up a shield booster large enough to boost it over 100 in one go. Pickups are the only way to increase your shield. Players usually spawn with 25 shield.

In multiplayer, the player can have up to 199 shield points, but this is not the case in singleplayer.
