Upgrades

Upgrades can be bought from either the blue PyroCorp Upgrade Station or red PyroCorp Weapon Store. The cost of upgrades can vary based on what type of upgrade it is, how many other upgrades you have previously bought, how many of the same upgrade you have previously bought and how much damage you've taken. Purchasing a blue, non-utility upgrade increases the cost of ALL other blue shop upgrades, as well as the Warranty upgrade cost.

From Blue Upgrade Station
Blue upgrades have an initial cost, plus increase in cost when any blue upgrade is bought. They further increase 10% for every 2 upgrades of the same type bought so specializing becomes very expensive. Total percentage increase for each of the same upgrade bought. Upgrade Cost = {Initial Cost + (Cost Increase x Number of Upgrades Bought Total)} x (100% + 10% for every 2 of the same upgrade)

E.g. The cost of the next Attack Power if you already bought 5 Attack Power and have bought 10 upgrades in total would be: (1000 + 5 x 1100) x 120% = 7800.

Utilities
Utilities have a fixed cost to purchase and do not increase the cost of other upgrades.
