But the players are behind and the skills are based on the bots that they have created.
Sorry but I think you got it wrong here, the skills and chances of winning aren't all based on the bot, the larger chance of winning the match is still based on the player/bot developer's skills in control the bot, the players are behind with a remote like pad which I believe controls both the movement and fighting skills of the bot.
Normally, except for the spinning weapons which are built into the bots, which causes some damage to their opponents when hit, except for this, there's not much the bot can do on its own without the owners control.
