Bots can be spawned with the sb command (see Donation in the cheats section) The command format is;
sb (1/2) [1 allies, 2 enemies] (Count) (Host Number) (Upgrade Count)
sb 1 1 Class01 5
This spawns 1 ally Equinox (Host) bot with 5 upgrades.
There is a Bots Learn option in the menu where you can allow bots to increase in skill. These have been used to beat game-modes and provide a nice combat skill level almost par to that of a player. *However, the bots learn feature usually learns to one character or boss at a time and therefore has a hard time adjusting to other characters.
(IMPORTANT NOTE: this does not count for any other AI besides bots) [Second note: I don’t know if what the bots learn saves after you leave. if you know edit this page or comment]
Most of the host bots, when faced with no target, will begin to either wander the arena randomly or start walking in a circle. The majority of the Melee based bots will try and get close to you, often walking in a circle around you.
