Big update! Tweaks to many settings across the board. Everything from tweaked melee/chainsaw range and cone of attack, to Common Infected numbers and spawn density, to horde times, to Special/Boss infected health/speed/damage/etc. Some are minor changes, others are not so minor.

In general, expect to fight more of everything, but have some of them easier to kill and a generally more fair yet more challenging experience.

Some more edits, including a tweak to this mod's Grenade Launcher stats, aimed at making it more useful. Its kill radius is wider now, but it's friendly fire radius is left untouched through some clever stat-based trickery. It'll also reliably kill a Charger in one shot, provided the grenade either directly hits it, or lands near its feet.

Minor tweak to zombie non-headshot multipliers.

Further tweaks to the same Common spawn variables.

Further tweaks to how Commons spawn. There will be slightly less of them at any given time, but they'll spawn slightly closer to the player too. This should maintain Commons fought, but should reduce overmobbing.

Added a host of new Hunter pounce-based variables, tweaking how the pounce itself works a bit.

My theory was correct. Commons don't gain health on higher difficulties, there's just a multiplier in place that gets lower the higher you go in difficulty. I've now reset it back to vanilla, except the Expert one, which now sits at 0.51 instead of 0.5. Commons will now have around 98 health. This is for my weapon scripts, and will have a nonexistent effect on regular gameplay.
Also decreased total ammo for the hunting rifle type to 200.

Major overhaul to Survivor Bot AI. I am now confident that my AI tweaks will match any other dedicated AI mod out there.
Also made a few gameplay tweaks, including an experimental tweak to Common non-headshot health where I put them all (for all difficulties) to Normal difficulty's value of 1.0.

Fixed an issue.

Rebalanced total carryable ammo for Autoshotgun ammo, Hunting Rifle ammo, and Sniper Rifle ammo.
Spent the last three hours recreating Common spawn amounts, density, and spawn range. There will now be many more wandering Commons than in vanilla, and you will need to actually think before running blindly through doorways etc...
