About the Game

36 distinctive defense towers

Lasers, missiles, machine guns, artillery, unmanned aerial vehicles, and so on, each have obvious advantages and disadvantages.

For instance, a heavy machine gun tower has a firing rate of 100 rounds per second, but its dispersion is extremely large.

Missiles have high damage and can be tracked, but their slow trajectory makes them prone to damage overflow.

You can choose the appropriate combination to complement each other's strengths.

Rich defense system

Unlike traditional tower defense games, this game places more emphasis on direct confrontation rather than simple passing interception.

The Vampire Tower has a high blood intake. As long as you attack and suck blood, you can take a large amount of damage.

Interception towers can intercept trajectories and even rebound trajectories.

The shield tower can block attacks.

Diverse economic systems

Killing enemies won't earn you resources, but you can obtain them in more ways.

1. Occupy mining machines.

2. Recover the Vampire tower attack to mine from enemies.

3. Interception towers can convert intercepted shells into resources.

4. Resource power stations can convert nearby electricity into income in a way similar to farming.

5. When the support station (a building providing manual skills) is idle, it will passively obtain resources.

Wait a moment.

Modification system

Before the game starts, you can choose different modification options for each type of tower. Different combinations have different effects.

Some have a higher cost but become stronger.

Some people sacrifice some attributes in exchange for making others stronger.

Diverse game difficulties

The leisure difficulty is very simple. Don't worry about not being able to pass.

When you have played many times and become familiar with the characteristics of various towers, you can increase the difficulty or add different buffs to the enemies.

There is also a pseudo-endless mode where you can challenge infinitely enhanced enemies.

Specialized system

Each type of unit has a unique specialized upgrade of up to 10 levels. Max-level units will be much stronger than initial units. (DPS may be dozens of times higher.

Very good optimization

In the later stage, with hundreds of units competing against each other, even without considering the gameplay, just watching the battles is very enjoyable. (At least that's what I think myself

Of course, I still hope that players can take advantage of the characteristics of different towers to challenge high difficulty levels. After all, this is a strategy game.

Three different game modes

1. Meat pigeon mode

Gradually unlock units and upgrade technologies by using technology points.

You can redeploy the units after each wave ends.

Each wave of enemies is random and has random factors. You can deploy your defense line according to the situation.

It is suitable for beginners to get familiar with the characteristics of various units.

2. Level mode

Accumulate resources to defeat the final Boss.

The enemy is fixed.

3. Survival Mode

Enemies are randomly refreshed, and large-scale enemies will be refreshed at regular intervals.

Suitable for challenging high difficulty and repeated play.
