TD3D

TD3D is a tower-defense game in a 3D environment. You build towers to stop enemies from reaching the end of their routes, which can rise or fall as well as move forward. Enemies emerge from a green ball and head for a red ball, and routes are generated randomly.

Build and upgrade towers

You can place towers to block enemies, or build them beside roads or on walls as the enemies grow stronger. Tower series each have three advancement paths, followed by three strengthening paths; advancement can also grant different abilities. You can choose low-level towers in large numbers or fewer, more powerful towers, and use wide-area attacks against small, fast-moving critters.

A talent tree lets you strengthen towers. Talent points are based on the highest number of kills you achieve in a single defense, regardless of level. Talents can boost attack power and special abilities, or give attacks effects that debuff enemies.

Enemies and routes

Enemies vary in size and speed, and some can walk on walls. Towers detect enemies by radius, so a tower may detect a large enemy at the edge of its range while missing a smaller one. Bullets that do not pursue their target can hit enemies directly behind it. Ordinary bullets cannot pass through walls, even when towers are built on them.

Achievement levels increase the wave flow level, letting you challenge and defend against more enemies. Enemies can attack from all directions.
