Featured in Twinfinite.net's 10 best Payday 2 mods

The vanilla teammate AI is basically designed to be a couple of guaranteed Jokered cops with health regen instead of being virtual recreations of actual players. This mod tweaks and changes certain aspects of the bots so they are both more useful and are more similar to human players. No longer will you have to deal with babysitting new players from the most recent Steam sale. Changes are as follows:

• Bots will automatically mark Tasers when they are tased
  
• Bots can dominate cops
  
• Bots can melee enemies, knocking them down and dealing half of their health in damage
  
• Bots can throw concussion grenades
  
• Bots can dominate, intimidate, and mark NPCs independently, rather than sharing a timer for these actions
  
• Additionally, bots will not mark enemies who are already marked, increasing the variety of marked enemies; the code for marking has also been improved for efficiency
  
• Furthermore, bots will now mark turrets
  
• Bots are included in the difficulty calculations by the game, allowing for a more human game experience
  
• Bots have had their "aim delay" and "focus delay" values set to 0, enabling them to aim and shoot at enemies immediately
  
• Bots can now hit targets at any range, including Snipers
  
• Bots have had their "run_start" and "run_stop" animations removed, enabling them to better keep up with players
  
• Bots will use human player outlines in offline mode
  
• Bots can shoot through one another and even hostages, so no more dead dominated cops
  
• Bots will not drop their bags if they can inspire the player or the bag is light enough to run with
  
• Further, bots' movement penalty when carrying bags is now similar to human players
  
• Bots will wear the Lightweight Ballistic Vest and either a doctor bag or ammo bag (chosen at random) to make them appear more human (note that the bags cannot be deployed and the armor does not increase their durability, both are purely cosmetic)
  
• Bots will automatically reload their weapons if they are out of combat and their magazines are at least half empty, rather than only reloading when their mags are totally dry
  
• Bots' targeting has been overhauled, prioritizing enemies based on distance and focusing on specials
  
• The bots' code for intimidating civilians has been improved and optimized for performance; bots will shout at civilians immediately if they are not on the floor, no matter what
  
• Bots' reactions have been streamlined and optimized for faster reflexes and target acquisition
  
• Many of these changes will also apply to Jokers, such as the improved targeting and reloading out of combat
  
• Bots will no longer attempt to revive teammates who are already being revived
  
• Bots will count for the "crew alive" experience and money bonus at the end of the heist in offline mode
  
• The following are completely customizable:
  
  • Health amount
    
  • Damage multiplier
    
  • Enabling dodging
    
  • Forcing instant custody upon being downed
    
  • Forcing arrests by Cloakers rather than downs
    
  • Disabling of warcries
    
  • Announcing low health (ie, asking for a doctor bag)
    
  • Enabling independent domination of cops, rather than just assisting with your own dominations
    
  • Enabling additional bots with the Big Lobby mod
    
  • Giving the bots near-instant reaction times
    
  • Forcing bots to mask up immediately when a loud sound is made, rather than waiting for the actual alarm
    
  • Improving and balancing bots' damage/accuracy/etc
    
  • Disabling dead enemy ammo pickups from bot kills
