The more you explore inStellar Blade, the more enemies you’ll encounter, the more loot you’ll find, and the more crates you’ll discover. While not all crates will be easy to open—some require you to find a passcode, while others need you to complete a small puzzle—certain types of crates will require you to have a hacking tool.

During your exploration of Eidos 7, especially in the Construction Zone area, you’ll come across your first high-security sealed chests in the game. Adam will comment that these chests require a hacking tool to open. And remember, this won’t be the last security chest you encounter, so having the hacking tool will be essential.
