Siege Machines are a special troop that can be used to carry and deploy your Clan Castle troops on the battlefield.
Siege Machines have very unique gameplay: they are used to transport and deploy the Clan Castle troops you received as a donation on the battlefield.
There are currently 4 Siege Machines on the game and they perform this task in a different way:
Once the Siege Machine is destroyed by enemy defenses, all Clan Castle troops will be released on the battlefield. This can also be done manually if you want to release the troops on a specific part of the enemy village.
Siege Machines can be deployed even if you don't have any Clan Castle troops donated inside.
All Siege Machines must be upgraded in the Laboratory, just like all other troops on the game.
All upgrades are done with Elixir.
