Before you can earn this achievement you must unlock the hearts decal
. This is typically random and you'll unlock it for a number of cars as you play the game. Either play loads of short exhibition games until it unlocks or be patient, it'll come.
Once you have the hearts decal, find the car which it applies to and apply it to that car
. Leave the garage.
You then need to set up an exhibition game against the AI. Go to Exhibition
and select any arena you like. It's useful for the game to be either 1v1 or 2v2
as it's less chaotic and gives you more chances to score. Don't forget to set their difficulty to All-Star
It's also helpful to set mutators
. The ones which I would recommend would be the goal limit being set to 1
which would ensure the game remains short and can be restarted upon failure. The second mutator I would recommend is the unlimited boost
as this will allow you to quickly hit your opponent on the attack or get back to defend, if necessary.
Once these settings have been configured, head into the game. I would recommend you play on the defensive until you see and opening and try to score
. If you do, the game should end and the achievement should pop. If they score, restart the game and try again.
