About Skill Trees in Tower Defense Simulator

The Skill Trees (Image via Roblox)

The Skill Tree system is fairly straightforward: you have four distinct tree types to choose from, where you can spend Coins for bonuses. These include Offense, Economy, Strategy, and Defense, each having multiple Skill Trees to purchase and activate. Skill Trees start at level 1 and go as high as level 50, depending on the chosen Skill.

The initial cost of each Skill Tree is low, but the more you invest in a particular tree, the more expensive its Skills will become. Conversely, the more you invest in the tree, the better your chosen unit becomes.

Thus, the Skill Tree system involves identifying the role of the chosen unit and buying upgrades accordingly. After all, it’s better to ration your Coins than to spend everything on one unit.
