The full description of the mod is in the changelog.
This mod makes several changes to bots to make them act more like human players and make them more reliable as teammates. They can use melee weapons, rescue you if you die, react quicker to a teammate being attacked by a special infected and much more.
Note: This version of the mod is ideal for servers and multiplayer with bots.
• Bots can use melee weapons.
• Bots will continue to play after you have died instead of ending the game.
• Bots will react much faster to a player being attacked by a special zombie.
• Bots can perform some simple actions, such as closing safe room doors.
• Bots will move around a player instead of shooting through them.
• Bots are much more likely to save their first aid kits for a player.
• Bots will try to stay in a tighter group with the player.
Works for all game modes.
