Bots usually run towards you and try to beat you to death with their bare hands. I don't think there's any programming for them to purchase using the tablet or even seek out items.
Taking existing maps and modifying the game rules could also work, but I'm not sure how many game rules can be changed via config/console and how many need to be done in hammer. Ideally this would be something I could exec on map load on any functioning DZ map.
