TerTD is a mix of tower defense and real-time strategy.

The main objective of TerTD is to annihilate the enemy.
Command-base is the most important building in the game.
Upon destruction by enemy, the player immediately loses the game.

The player can build various types of towers and choose your favorite upgrades.
These towers must be connected to the energy network which has at least one reactor or the command-base.

Additionally, the player must monitor energy production and consumption.
If more energy is consumed than gained, weapons won't be able to be recharged as quickly.

Hint:
Let's use the booster well.
The booster strengthens the turret and drone base.

The combination of high cost tower and red booster, the combination of drone and blue booster, is effective.
