Total Damage (aka, "How good are you at not taking damage?" ) is a tiny add-on I created 3 years ago, and later revisited and gave it a revamp (better code and graphics). It simply displays the total damage you took through out your campaign of a map or mapset on the screen. Optionally, it'll also display armor damage (the option is off by default. To toggle it on, type: "nc_td_armor_toggle 1" in the console [without the quotes]).
Spoiler: Screenshot (just to avoid confusion, the add-on is not part of the HUD you see here)
Spoiler: Why did you create this silly thing, Blue Shadow?I played through all four episodes of Doom and also Doom 2 (vanilla, without gameplay mods) on Ultra-Violence difficulty, achieving 100% kills, items and secrets. This is how much damage I took by the end of each game (does anyone think they can do better? ):
Spoiler: Playthrough ResultsNote: Due to how it's coded, the damage calculated isn't 100% accurate at times; this only happens if you take damage and heal in the very same tic. Still, the results should be accurate enough, I'd say.
