Pretty unlucky day. You are trapped in a robot war in which there are humans (robots are alive so even though they are not controlled by humans they will still behave) Fortunately you met bt-7274 and he need a battery to make it move freely. bt-7274 tells you to go get the battery (the location is quite far and you have to pass through several monsters)

bt-7274 Just staring at you while he can't do anything due last fight especially need a battery
