Upgrades

This game is very likely the first incremental tower defense game ever created. An incremental game is one where you achieve many upgrades in quick succession during the entire gameplay. Each tower has 3 ranks that the player can upgrade to directly (2 upgrades each). Each of those ranks have automatic mini upgrades as they achieve a certain amount of damage. Each rank has more mini upgrades than the previous rank. As you make progress, unlock the Factory tower to unleash even more upgrades that must be discovered by the player in game. Can you unlock the golden tower?

Towers

10 towers with 3 ranks each with more upgrades to be discovered in game (with the factory tower). Each tower serves a different purpose that the player can mix and match to optimize their strategy. Get automatic mini upgrades for well placed towers.
