Defend your fortress in the Cube Tower. Place weapons to destroy invading aliens and upgrade those weapons to high level for higher performance.
Your base contains a secret that the aliens desperately want. And your task is to protect this secret box from these robbers. Arrange the weapons placed on the way that the aliens pass to destroy them. Select the lands and place your weapons on them.
The top of the screen weapons represents the energy for you to restore your. When the energy reaches above level two, you can expand the weapons and place them in many places. Or upgrade weapons when mana reaches four so your weapons work faster and kill targets faster. Make the most of your land, place as many low level weapons as possible then upgrade weapons near the first secret chest.
You only have 6 lives for a play. Lives are lost when the secret box is invaded by aliens. And when all 6 lives are used up, the game will also be over. By all means kill all the aliens before you run out of lives.
The game has a total of 18 levels. The level will be more difficult when the enemies penetrate more than you have limited weapons and their kill speed can't keep up and completely kill the intruder. This requires you to have the right strategies to survive to the end.
Use the mouse to place the logical bases.
