Upgrade

Upgrades grant access to new food items or Powerups in Story Mode in Burger Shop and Burger Shop 2.

Overview
Upgrades are available from Level 2 on in both games. Upgrades provide new food items or upgraded recipes for current items. Upgrades appear before each level in groups of three. The player then chooses one of the three as the upgrade for that level. The player can change the upgrade available when replaying the level, but they must reset all future progress. Because upgrades are freely chosen by the player, the upgrades available vary greatly depending on which upgrades the player has chosen. In the second game, the upgrades available are also influenced by what meal will be served at the next level.

In general, drinks and basic side items such as fries will be among the first upgrades available. Toppings for burgers and sandwiches will generally come before increased sandwich sizes. Once the first upgrade for a specific category is unlocked, later upgrades in that category can appear. For example, Onion Rings will not be available as an upgrade until French Fries are unlocked.

In certain early levels, upgrades give access to items for BurgerTron 2000, such as Burgerbot, a side table to place food on, or access to lollipops or cookies. Powerups are also available as upgrades, with the player choosing from one of three powerups.
