Shadow armor

The Shadow armor is a powerup in Strife. It is Strife's equivalent to Doom's partial invisibility powerup. However, it does not protect the player like armor as the name implies.

Occasionally, Acolytes have shadow armor, making them harder to see and hit. Rarely, other enemies also appear with the effect, including some stalkers and sentinels - this is controlled using bitflags in the THINGS lump.

You can hold a maximum of two. If a second shadow armor is activated while already using one, the player becomes completely invisible. In this state, the player's weapon is also rendered with an inverse colormap, similar to the invulnerability effect in Doom (however, the player is not invulnerable). Enemies will have even worse aim when firing at the player or other targets which have this doubled effect.
