Upgrades are tremendously expensive. That’s why so few people have fully maxed hangars, and this huge investment is what separates the big whales from the little dolphins. It takes almost 13 days and over 48 million silver to upgrade a single Taran to level 12. To make your Taran Mark2, you need to spend 500 gold AND repeat the time and silver investment. One weapon to Mark2 … 96M silver, 500 gold, and 26 days. To achieve Mark 2 level 12 with all the items in Addictive’s hangar would require almost 2.1 billion silver and 612.6 days - and obviously, Addictive did not wait for almost two years for his bread to bake. Gold, for instant upgrades, can be purchased at the rate of 14,500 Au for $99.99 (145 Au per dollar). Silver, for starting the upgrade process, can be purchased with gold at the rate of 18500 Au for 50M Ag (391,910 Ag per dollar).
