The first thing you need to do is to create yourself a robot, obviously. To do this go to Assembly Mode and select yourself any robot. Once you’ve done that, go to Customize and and then any part you want (the Head for instance), then select designer. You will get a pop-up notification telling you that this is only a sample version (unless you’ve bought the DLC in advance). Simply proceed as this won’t prevent you from getting the achievement. Select Area 1, then color and then continue to choose any color you want from the Palette. After you’ve done this go down and press “Save color”. When you press there, you will see all these white boxes, these are your “save boxes”. Simply choose any one you want to save your customization. When you’ve done that, exit out to the main menu (Keep tapping B) and you should unlock:

Customize and save a robot to a garage.
- Now, you’re ready for your first fight. Go into the Match Modes and choose Underworld 1st Stage (the only one available for now). Fight off your opponent with the tips I previously gave you, and you should be fine. After winning your first battle, you will unlock:

Proceed to winning games, and once again, if you can’t beat a certain robot, just replay previous battles to earn some TBR, catching up on your nemesis. Each battle gives you credits. Use these on new body parts to make your robot even stronger. Make sure to Quick Repair your robot after each fight. After you’ve completed Underworld 1st & 2nd stage, you should unlock:

You’ve now made it to the WRB. Keep beating robots as they come and go. Once you’ve completed both the first and second stage in WRB, you’ll be granted:

Congratulations! You’ve now completed Real Steel!
