I would like bot in forge and custom games to test maps and game modes, or to do simple training also, when you are alone.
They should have settings regarding mobility and difficulty:
Movements: On/off
In off mode they are still. Useful for testing the headshots needed to kill with a specific weapon, or grenade and sniper training modes.
Weapons: Off/On
With movement on and weapon off, they moves in the map without shooting. In on mode they shoot you. I should be able to choose which weapons to equip them.
Difficulty: easy/normal/hard/legendary
In legendary mode, they should be better than human champions: always perfect kill, realistic strafe, perfect grenade throwing etc…
