Hollow

Hollow is one of two new skulls added in Halo: Spartan Assault.

Effect
The player lacks any HP, and thus will die as soon as their shield drops. This renders them significantly more vulnerable to the Covenant as they can take far less punishment.

Trivia

 * When combined with the Pacifist skull, it forms a lethal effect; the player can kill themselves by simply shooting. This is quite easily the most difficult of skull combos in the game, but aptly, it also provides the highest multiplier.
