The Backpack is what players use to store their items, models, bricks and behaviors on their Minifigure. In the Alpha and early Beta, only items were stored in the backpack; models, bricks, and behaviors were stored in a Brick Box.

Backpack Size

All players begin playing LEGO Universe with 20 spaces in their backpacks; however, they can complete missions or achievements that grant extra backpack space. Most rewards give 4 extra space, but others exist that grant two or only one.

It is possible to gain 102 backpack slots through missions and achievements. Added with the beginning slots, the 20 that Dr. Overbuild gave in anticipation of the Vault, and the 40 earned through leveling, a player can have up to 182 backpack slots.

In Beta, it was possible to get more Model space in the Backpack using Rigged Model Packs from Gnarled Forest achievements. This was removed in mid-Beta.
