I wish you could be stealthy in this game, I mean, you could be behind someone and they instantly turn around. I want silenced guns and 1 hit kill back stabs, some sort of way to be stealthy!
You should be able to "rent", I should say, the workers for resources. Like, for X amount of resources, he can do lets say 3 upgrades. Just a suggestion instead of having to buy the workers for shiny.
