Video games have had an armor mechanic since way back but it seems like a lot of games these days are adding it in as well. They all have their different way of going about it though. Fortnite uses its shield potions that magically give you a barrier. Warzone goes about it in a more realistic way with plates, although those plates are just about as good as paper…
DOOM is a classic where armor is all over the ground. Not sure how stacking helmets works though.
GTA 5 has the most realistic mechanic where you actually have to go and get it. For once GTA is the most realistic in my series!
