This mod makes this game more challenging.

I just realised how badly the original hl2 is broken. For example: strider, sniper, soldier - They were all reworked in episode 1 and they works very well in episode 2. But, they still broken in original hl2. When Valve update hl2 in 2010 they just added shotgun soldier skin and slightly improve A.I. But, they did not add their ar2 accuracy and energy ball instakill for elites. Those things that have been added in episode 1. And this the only good stuff what we can get from episodes. What a shame...

This is not some kind of ultra-hard mode, it's rather an attempt to make the original balance more... balanced?

If you think that the game is too easy for you, I think this mod is perfect for you.
Note: this mod does not improve AI, enemies accuracy/reaction or something like this. Only damage/hp/ammo values, which are available through the developer console.

You can choose (in game) any difficulty level:

Easy - originally "old" medium level.
Medium - originally "old" hard level.
Hard - New hard mode (actually from episode 1 & 2).

Valve npc's weapons damage system (aka 3 damage per hit from smg1, ar2, pistol, etc...) did not change at all (because, it's works very well), but, the damage multiplier has been changed.

Updated difficulty system:

1 - easy. 2 - medium. 3 - hard.

1.00 = 100 %

Ammo pickups          
sk_ammo_qty_scale1  "1.00"  (valve - 1.2)
sk_ammo_qty_scale2  "1.00"  (valve - 1)
sk_ammo_qty_scale3  "1.00"  (valve - 0.6)

Damage from all sources (npcs, fall damage, etc...)
sk_dmg_take_scale1  "1.00" (valve - 0.5)
sk_dmg_take_scale2  "1.50" (valve - 1.0)
sk_dmg_take_scale3  "2.00" (valve - 1.5/2.0 - hl2/episodic)

Damage to the npc's
sk_dmg_inflict_scale1  "1.25"
sk_dmg_inflict_scale2  "1.00"
sk_dmg_inflict_scale3  "0.75"

Interesting Facts:

* Strider in hl2 is overpowered, 15 dmg per shot, but first shot actually does not cause damage; in episode 1&2 - 5 dmg per hit, but, with better accuracy and firing speed. Also, in the episode one, damage from strider depends on the player's health:
the less health - the less damage (from 5 to 2).

* Episodic combine soldiers has better accurace with pulse-rifle.

* Episodic combine elites has ability to insta kill human-sized npc's with their ar2 energy ball attack, this is similar for player pulse-rifle alt-fire attack.
But, in hl2 they always make "base" damage to npc's and cannot kill poison headcrab with single energy ball.

* Sniper in hl2 always make "base" damage to player, regardless of difficulty level.
When in episode 1&2 he make double shot plus additional damage depending on the difficulty level,
 "Base damage" + "base damage" x "damage multiplier" = "total damage".

* Antlion Guard has damage resistance from bullets (-75%) and buckshot (-50%).

* Combine Soldiers and Zombies receive only x2 damage from headshot.
When Metrocop, Citizen receive x3 damage.

* Zombies has damage resistance from bullets (-50) and buckshot (-60%).
* Damage resistance does not affects to headshots.

* Hunter receives additional damage (+15%) from 357 regardless of bullets resistance.(Crossbow bolts have the same damage penalty as bullets - only for hunter).

Well, thats all.

Have fun.                                                                                         P.S. Sorry for bad English.

    Pretty good, but it does not go too far, maybe if it increases the damage of the smg in the npcs, and increases the accuracy of the ar2 in short and medium distances (in long only the npcs), but the real problem is the AI

    Sorry for my English
