Meaning all damage stats in general for any weapon. If a gun is at 30, a melee weapon is 50, and a grenade is 150 does this mean that the gun does as much as a grenade after 5 shots or the melee weapon does the same exact amount after 3 hits? So this damage stat is completely universal in the game? Or does the stat apply to certain types of weapon categories separately?

Should be the same across the board, but remember that you have to adjust for DMG resistance. So if a dude has DR20, 5 shots from your gun till only do 50 dmg total, while one hit from a grenade will do 130 and 3 hits from a melee weapon will do 90.

Ah thank you. Also on an irrelevant note what platform do you play on?

The grenade does more against armored targets.

Also note that grenades and explosive weapons do splash damage to other enemies in their radius, so they can potentially do a LOT more damage if you have multiple bogeys.

Armor does not work like a straight reduction in this game.

It is scaled to the damage,

if armor = base damage the reduction is 50%

so for 50 vs 150 damage

an enemy with 50 armor takes 25 damage from the first attack, and ~112 from the second

an enemy with 100 armor takes ~16.6 damage from the first, and ~90.3 from the second

an enemy with 150 armor takes 12.5 damage from the first, and 75 from the second

In theory, an enemy with 5000 armor would take 1 damage from the first, and ~4.4 from the second.
