Splody

It’s best to select a large map with lots of destructible blocks like Sanatorium. You’ll need to destroy as many blocks as possible and collect as many bomb power-ups to allow you to place more bombs at once. You should also get as many speed power-ups and the dino power up to move faster. Once you have collected enough bomb power-ups and are quick enough, just go around placing as many bombs as possible and you should be able to unlock this.
