Big Tree

Big Tree (bzm_bigtree) is the first Bot Zombie Mod map in Counter-Strike Online.

Overview[]

Big Tree is the first map that supports the Zombie Bot game mode. It promotes to basic Zombie: The Original system with the addition of bots. Bot navigation has been tweaked a bit so that it is compatible with Zombie modes. These modifications to bots are:

  • New function: zombie safe area.
