This tutorial will explain how you can unlock the Double Dug-In trophy in Astro Bot. You can do so by taking the following steps:
1. Make your way to Wormy Passage.
2. Go through the beginning of the level until you see two small wormy enemies pop up from the ground.
3. You need to get in halfway between the two and then hold the L2 and R2 buttons simultaneously to grab their faces.
4. You can then move backwards to defeat both to get this trophy to unlock.
