You must defeat the bots in a 1 vs. 1 Exhibition match on the Unfair difficulty with a heart decal equipped on your battlecar. You must win the match without making any mistakes. If you miss a shot, the bot will almost always score a goal. Remain inside your goal until the bot makes a shot against your goal. Then, charge using your boost and clear the ball towards their goal. Do not jump to make the shot. With good aim, you can score all the way from your own goal. If you missed the goal and the ball moves to their side of the field, collect a 100% refuel for the boost and immediately return inside your goal and try again. If you hit the ball but it did not reach the bot's side of the field, get as many small boosts as possible on the way to your goal, then immediately return inside your goal and try again. If the ball gets close to their goal and you are absolutely sure that you can get it in, charge forward and do so. However, if you miss, the bot will almost always score against you. Repeat this process until you win the match to get the "Hot Shot, Part Two" achievement.
