Rocket League

This is easiest with a second controller, but you can do this with a rookie bot just as easily.

Start a civilized rumble exhibition 1v1 match, unlimited time and unlimited score if you want to give yourself as many opportunities as you need. Use all the powerups until you get the Ice Ball powerup, once you have it, use your second controller to shoot at you (or wait for the bot to attack you.) then once it gets right before the barrier hit to freeze the ball before it enters your goal.

BETTER SETTINGS for SOLO METHOD, ONE CONTROLLER:

• Exhibition Match
• Game Mode: RUMBLE
• Arena: ANY
• Team Size: 3v3 recommended
• Bot Difficulty: PRO or ALL-STAR
• Match Length/Max Score: UNLIMITED
• Rumble: CIVILIZED

Because Rookie bots are stupid, they take forever to set up shots. And 1v1 will have your opponent camping in his goal for half the match. Better to make them smarter — Pro or All-Star — and more plentiful, so that shots on goal occur more frequently. All-Star 3v3 worked best for me; there's more action than 2v2 but it's not as chaotic as 4v4.

If you set the Rumble mutator to Civilized, it pulls from a smaller pool of power-ups which includes only the ball-oriented ones and excludes the car-attack-oriented ones. This means Ice Ball will come up more often, giving you more opportunities to get this done.

You must freeze the ball with after it is considered to be a shot on your goal. Freeze it just before, or as, it is crossing the goal's threshold. To be done correctly, the freezing of the ball must register as a Save or an Epic Save. The achievement will pop during the match immediately after you succeed.

This is the Ice Ball power-up:




If you wanna do this with two controllers, check out Tyboy17's video, but remember to use the Civilized mutator!

I have made a video guide as well.

I found the easiest way to do this, at least for me, was to set up a match with the following:

• Exhibition Match
• Game Mode: Rumble on any arena
• Bot Difficulty: Unfair (1v2)
• Rumble: Civilized

I found that the solution posted by "z 4assed monkey" was a good starting ground, at least in setting the rumble to civilized. I find that the biggest problem I had with their solution was that the bots on your team do a good job of defending you, but you don't really want that.

Having 1v2 means that you have two bots on the opponent team that are constantly trying to score goals on you, which is much easier to defend when you are alone. The biggest challenge was defending the goal while you wait for the Ice Ball power up. There were multiple opportunities for them to score, but just defend yourself until you're able to get the power up. There were many of attempts where the ball just rolled into the goal and I did not have the power up. I suggest defending the goal and saving (rather than letting them score) and sit in your goal until you can get the power up, that way you can watch them and learn how they shoot, etc.

I was able to unlock this within 5 minutes of starting the match.
