Real Steel

The TBR is Total Battle Rating. You can see this number at the top of your stats in the assembly menu and at the bottom of the rank fight lobby, it's the number that is in the blue/red boxes. This goes up and down as you win/lose.

To get this achievement you need to have one person win until his number is double the other persons, the one winning will need to periodically repair themselves to get the TBR up. Then the person with the lower TBR will win and achievement unlocked. The person going for the achievement do not repair your self at all as this will raise your TBR. After the first person gets the achievement the second person will equip their starting stuff (arms, legs, etc.) and the first person repairs and you just do the same thing again.

A note a quick way to boost your TBR is to go into assembly mode and then go to shop and buy better equipment/parts for your robot. The new TBR will flash yellow on the right side of the screen and your current TBR is white.

Hope this helps someone.

this is verry simple to do and is best done when going for your ranked wins have your partner pick his best bot and you bick your worst bot let him beat you until you are in need of alot of repair than once you are verry damaged beat his bot and you should unlock the achievement just make sure to compare your stats and his
