TTK Rebalance

A cfg set that's low-key kinda based on COD: Modern Warfare 2019's veteran campaign difficulty.

Lowered TTK across the board (AKA everyone dies much, much quicker), with other changes depending on the chosen difficulty level.
Default combine can be killed with one pistol headshot, while armored variants take a fair few more rounds.
Zombies can usually be killed with three pistol headshots (though I suggest "Merciless" by Cuser, more on that later).

Ammunition capacity is drastically reduced to both balance damage and (somewhat) realistically represent what one could easily store in their pockets (or fumble out of a small backpack) and if you try and store more than that the game will eat it (unfortunate limitation). Normal is one pistol mag and three shotgun shells, easy is three and seven, and hard is whatever can fit in your gun.
Enemy behavior is slightly altered in some areas, such as the deliberate miss chance for headcrab attacks (which varies by difficulty, normal being "0.1").
All of this varies by difficulty level, but the default is normal.




I suggest combining this with the "Merciless" addon by Cuser, which makes enemies smarter and more deadly. As good as HL:A is, its AI doesn't seem all that smart with quick decisions, and sometimes combine just stare into your eyes while you slowly drag your iron sights onto their head. Merciless solves these problems with TTK, and balances out a few things that don't have a compromise that I know the half of how to implement, but it may be difficult to combine the two.
At the moment, I think maybe just installing and/or enabling this addon after merciless may properly combine the two without much hassle, but if you know how to unpack and repack a .vpk, you can just rip the cfg section out of Merciless and it'll work fine.
