Summary

Bubb Towers are perhaps the most similar in function to that of its human counterpart, except that a door into the tower is not required: Bubbs can float into the tower, and built-in weaponry (once piloted by a crew of Bubbs) can keep encroaching enemies from floating or climbing in.

The boulder-like stones that this tower spits out drive enemy armies into panic. Humans are generally resilient enough, but Bubbs will flee rather quickly. These towers do need to be manned to fire however, the more Bubbs garrisoned means a faster fire rate.

Tactics

Although the Tower fire rate can stack infinitely with tech upgrades, there are diminishing returns after the first 2 Bubbs so it is always better to build more towers instead.

Keep your towers defended, as when it is destroyed the Bubbs inside may be left vulnerable.

Trivia

Towers originally had boosted damage output when garrisonned. This is still technically true except it will not fire when empty and scales the fire rate instead of the damage with more Bubbs.
