What each system does

• Partner type: in the Coop Bot Menu, choose Bot player or Enemy ally. For an enemy ally, pick the enemy from the list.
• Orders: tap H with the cursor over something. The bot attacks an enemy, picks up an item, interacts with a chest or lever, or smashes a breakable. If there is nothing under the cursor, it comes to you.
• Combat: the bot aims ahead of moving enemies, reloads, handles charge weapons, and can use blanks and active items.
• Dodging: the bot weaves or rolls away from incoming bullets, and avoids pits, fire, harmful goop and danger zones.
• Cover: the bot hides when under fire, reloading or hurt, flips nearby tables, and peeks out to shoot. Set how often it hides with Cover preference in the Coop Bot Menu.
• Weapon list: press Y and click the weapon the bot should hold. The screen dims and you can't shoot while the list is open. The bot keeps every weapon it picks up, up to the inventory limit.
• Trading: swaps are always two-way. Starting weapons and passive items can't be traded.
• Co-op rules: the bot uses doors and elevators. If it dies it becomes a ghost until revived, and the camera follows it if you are down. If you die outside a boss room, the run ends as in single player.
• Saving: the bot is saved with your run, so Continue brings it back with its character and gear. A dismissed bot keeps its gear when you summon it again in the same run, even if you close the game.
• Enemy ally: it follows you between rooms, shoots stronger blue bullets, dodges, takes cover and keeps its distance. Enemies target it too, and it doesn't count towards clearing a room. If it dies, it returns once the room is clear. It doesn't take orders or carry an inventory, and it disappears when the floor changes.
