Invulnerability (Doom 2016)

The Invulnerability sphere is a returning powerup that appears in DOOM. It is green in color.

In-Game Description
UAC REPORT FILE: 98THE72Z

''When it is absorbed, this stimulant diffuses Argent plasma to the basal layer below the dermis creating a tough film of bioplasma beneath the skin that protects the user from external attacks. This can make the demon almost entirely invulnerable until the plasma has been dissipated through repeated punishment. The bioplasma comes into direct contact with the nerve cells beneath the skin which causes excruciating pain throughout the process. This increases the likelihood that, in the throes of agonizing torment, the mindless demon will try to attack targets that are clearly beyond their ability.''

Combat Characteristics
When the player picks up a Invulnerability powerup, the edges of the screen gain a green tinge. The effect lasts for approximately ten seconds.

Tactical Analysis
Invulnerability grants a brief period of invincibility against enemy attacks. As in Doom 3, this effect is not absolute, and instant-death sources of damage such as lethal falls or crushing objects can still kill the player. While the sphere is active, the player's view is slightly obscured at the fringes by a green haze, and a greenish light can be seen as a sheath over the player's weapons.

The invulnerability power-up is not available for placement in SnapMap. Regeneration is the closest available item in that mode.
