True Survival is a go-to overhaul mod for those who appreciate immersion. Undead Legacy and ComSenMod were also great for this same reason, in the past. @Spider Thank you for all your time investment!
Perhaps it's not an issue for you, but only one problem to date: ridiculous base Health ranges on some of the new "bullet sponge" zeds. If "base_set" for "HealthMax" was somehow limited by/tied to Gamestage, or simply comparative to vanilla HealthMax values, IMHO True Survival would be much more balanced. Bearing in mind, a value of "80,120" or "100" represents a fully healed NPC or average adult human body. Zeds should NOT have several hundreds, or even thousands, of Health at early gamestages.
Sometimes discretion is the better part of valor and players just need to to learn to run. However, I cannot count how many times one of these new bullet sponges spawned on day 1 or 2. Almost always have to burn through an entire belt full of improvised weapons and tools (headshot only), just to get one to stop chasing...
