SimpleTD

SimpleTD is a tower defense game in which you protect a central base from waves of enemies. You place defensive towers from your backpack, defeat attackers to collect resources, and spend those resources in a shop on better weapons. You also need to resupply when ammunition runs out, upgrade skills to increase your towers’ firepower, and complete time-limited missions for exclusive rewards.

Build your defenses

You can build and demolish defenses, manage resources, and combine skills as you adapt to attacks. Hundreds of tactics are available, with dozens of special warriors, weapons and status effects. Cat Warriors deal double damage, while Dragon Warriors hit twice. Weapons include the Mind Controller, which converts enemy units, and the Teleport Gun, which flings foes across the map. Freeze, Fire and Electric Shock effects can trigger chain reactions, while thunderstorms and acid rain change battle conditions.

You can relocate your base, take on 100-wave survival, reinforce defenses with a Diamond Hammer, and use an Amulet to revive units. Magic Mirrors copy enemy units, Spell Books unleash ultimate skills, and Interaction Mode lets you move buildings or set up teleporters.

Customize your tactics

Rubies strengthen attacks, Black Gems increase attack speed, and the Iron Watermelon’s Iron Wall and Holy Water’s Divine statuses help shape your defenses. The game includes adjustable difficulty and auto-save. Mouse-wheel zoom, spacebar pausing and hotkeys support direct control, alongside the option to customize your approach and continue using earlier strategies as you progress.
