[OBSOLETE] Icebreaker Achievement Guide (The Ice Cave)

How to get the Icebreaker achievement for The Ice Cave in the Arcade.

Disclaimer

This isn't a very consistent way to get every tile in The Ice Cave, this is just how I got the achievement.
This isn't meant for Unit grinding, this arcade cabinet doesn't give many Units anyway.
Having a crosshair will really help, my monitor has an option to enable one, you could also just use a Post-It Note or something.

Explanation Through Text

Firstly, you don't need to look at the snowballs to grab them, you can just press E (or whatever key you use) to pick up a snowball.
The main part of this strategy is to throw all the snowballs at the closest tiles near you, and hope that the snowballs will hit the tiles near the back.
If there are a couple tiles left, you can manually aim at them if you have enough snowballs left.
If a tile needs to be hit at the very back, use the bounce pad.

As you can see I get pretty lucky, but you will need luck.

Hope this works for you, this achievement can be infuriating.
