Getting studs in LEGO Batman certainly isn't the most difficult task in the world, but it sure is satisfying as hell. And what's more satisfying than being able to get filthy rich in the crime ridden streets of Gotham? Well, this simple tip will get you a re-usable cache of studs that pays out thousands each time you use it.
Here's How To Unlock The Stud Cache In LEGO Batman: Legacy Of The Dark Knight
Overview
LEGO Games Survey
Getting free studs of course won't come without a catch, and in our case it comes from the Extras tab within your pause menu. Simply head over to it, and look for the option that mentions the LEGO Group Online Survey.
This is a short, 2 - 3 minute survey that will ask you about your overall experience playing LEGO Batman, but also if it makes you want to buy any future LEGO Products.


Regardless of how truthful your answers are here, or how big of a fan they make you seem, you'll be rewarded at the end of this survey with a code which can be redeemed either in the Extras menu or at the title screen to unlock a pretty unique reward within the game.

What do you get for the survey?
Once redeemed, restart your game completely. The next time you log in, you'll be automatically granted the Stud Cache for your Batcave which serves as an interactable object.

Interacting with this cache will grant you a large burst of studs for free, and the best part about this interactable, is that it can be used repeatedly, each time you travel to the cave.
The best part about this cache of studs, is that it scales with your exploration upgrades for picking up studs! My first opening gave me over 20K studs, and that's only with 1 upgrade!
