This mod makes the health turn red whenever the player's total health is equal or below 225 (which is a one-shot kill from a heavy swat in DSOD.). It also takes damage reduction skills / perk decks in mind when calculating the one-shot health.

Currently tested and working with the vanilla game, CustomHUD, VoidUI, PocoHUD and MUI.

Any HUD mod that keeps the vanilla circle should be compatible too, but feel free to let me know if any do not work with this.

Health amount is configurable ingame via the options menu.

Idiosyncrasy had the original idea. I made it into a mod.

Want any HUD mod made compatible? Let me know in the mod's comments!
