Most of the game elements in this game is white labeled from Boom Beach with the exception of sicarios. BB is a free player game in that a player can reach the highest level without spending $, I've done that. However the design of narcos is all upgrades need 2-3X higher resources, and has low victory sicario% (BB can have >200% on rewards if getting right statues etc.) which means a number of Narcos upgrades beyond L16 finca will need to wait for guerilla events for upgrades otherwise not impossible. It's also mention in other threads here that clearing map + war rewards does not get the resources for e.g 2M+ Wood, stone, iron for 1 upgrade. Pls get real. NO GOLD means NO UPGRADESNo, there is no limit. You just need to wait longer periods of time as you progress.
