Based on L4D2 realism mode. Makes the game considerebly harder togeather with the economy, It's not unfair but more challenging.
Enemies damage you faster, outlines are also non existent recommened only for experienced players you have to work from memory.

Put both files in Mods folder (delete the "disable outlines HARDCORE" folder if it's annoying)

Features:

• Grace peroid decreased: It's a hidden game stat. basically it dictates how often you take damage, on ovk it's 0,35s )but with certain perk actions like grinder healing it drops)
  Enemies are able to deal damage much faster.

• Harder economy: some loot values changed, money, goats, jewerly ..etc have more value, weapons, slots, preplanning, assest are more expensive so you have to be more careful while planning the heist. money makes sense basically. (based ony my Rebalanced Economy mod, but tweaked)

• No outlines: this is something i only recommened if you know the game. objectives, enemies, teammates... NOTHING has outlines. The game looks better, but you have to work from memory and it's challenging to find interactions and bags scattered around. ( delete the disabled outlines Hardcore folder if you find it annoying )

• Disabled second wind effect: no annoying speed boost or get out of jail free card when armor is broken

Tell me the issues or ideas in comments.
Have fun heisters!
