This mod adds the Pressurized Air Tank Upgrade, allowing Sophisticated Backpacks to store pressurized air from Create. Air stored in a backpack can be used by Diving Helmets, Potato Cannons, Create: Jetpack, and potentially other compatible third-party utilities.
The upgrade converts two rows of inventory slots into a pressurized air tank. Its capacity scales with the backpack's tier and installed Stack Upgrades. Each backpack can contain only one Pressurized Air Tank Upgrade, and it cannot be installed alongside an FE Battery Upgrade.
Backpacks equipped with a Pressurized Air Tank Upgrade have rotating cogs rendered on them. When placed in the world, they can be connected to a rotating shaft and recharged with pressurized air, much like Create's Copper Backtanks. Note that most backpack functionality is temporarily disabled while the backpack is being charged.
This mod also includes compatibility with Create: Jetpack. When Create: Jetpack is installed, you can craft a Jetpack Upgrade that allows a backpack to function as a jetpack without providing any armor protection. Its behavior is governed by the Create: Jetpack configuration.
