Communication Tower

The clan communication tower allows you to launch clan convoys. These clan convoys work similarly to regular convoys, but are limited to only members of your clan and offer special rewards. Each convoy has five difficulty levels, and each can be fought once per week. See the convoy page for a full list of details.

At the moment there are five clan convoys available. The "Doom Hammer" convoy is unlocked at building level 1, and the rest are available once the building reaches level 2.
 * "Doom Hammer" walking machine
 * "Warrington" frigate
 * "Genofrost" armored truck
 * "Warrior" walking machine
 * "Wrath of God" bunker

The gallery below shows the communication tower at all different levels.

The costs to build and upgrade the building are as follows. Note that although the building can be upgraded to level 10, at the moment there is no benefit to upgrading it past level 2. Like other clan buildings, upgrading this building requires first unlocking the upgrade by contributing building blueprints, which can be obtained from completing clan tasks. The blueprints are not consumed, so when you are unlocking a new upgrade, you start with the number of blueprints from the previous level. Once the upgrade is unlocked, then clan members can contribute resources to the upgrade as normal.
