Default Difficulty Settings (thcoop4)

Differences between Expert and Hard

Expert mode loads the l4d_ragdoll_fader plugin, which makes zombie corpses disappear instantly

Tank Health

This repo uses l4dinfectedbots(2025-1-7) to control tank health

• When player count > 4:
  • Easy / Normal: 6000 + (player_count - 4) * 750
  • Hard / Expert: 8000 + (player_count - 4) * 1500
• When player count <= 4, tank health is reduced proportionally:
  • Easy / Normal: 6000 * (player_count / 4)
  • Hard / Expert: 8000 * (player_count / 4)

Special Infected Spawn Time

25-35 seconds, slightly longer when player count < 4

Special Infected Count

By default, players cannot control special infected. Quantities refer to sourcemod/data/l4dinfectedbots/thcoop4_xxx.cfg
Default configuration recommends player count ≤ 14

Special Infected Control Configuration

Refer to sourcemod/data/l4dinfectedbots/xxx.cfg, where xxx is the game mode. This repo adds the thcoop4 mode
thcoop4normal mode loads configurations from thcoop4_normal.cfg, other modes loads configurations from thcoop4_hard.cfg
For other unlisted configurations, you can add a my_mode.cfg file and set cvar l4d_infectedbots_read_data "my_mode" to load it
