Materials

Materials are one of the main resources used to purchase certain important upgrades such as the number of workers and different skills. It can be acquired through exploration in varying amounts.

Acquisition
Materials can only(?) be acquired through exploration. Each area will give a different amount of Materials on average, and each opponent may give more or less materials depending on difficulty. Later areas give more Materials per opponent fought than earlier ones, but cost more Fuel to explore.

Upgrades
Materials can be used for important and powerful upgrades, such as increasing the Worker cap and upgrading boosts on manual ammo production.

Workers
Materials can be used to increase the maximum Worker capacity. Each upgrade will increase the cap by five Workers. The formula to calculate the cost in materials is: cost = 20L + 10 where L is the current level of the upgrade (starts at 0).

Boosts
Materials can also be used to increase the boosts when producing ammo. These boosts include:
 * Boost effect - how much of the production time is skipped; given as percentage
 * Boost size - how much of the production bar allows to boost production; given as percentage
 * Production volume - how much ammo is made at once; given as integer or multiplier
