Tentacle

The Tentacle is one of the most expensive units which could be spammed indefinitely, costing 850 to deploy and 2,100 to purchase. It appears to be a mechanical flying octopus with lights on its tentacles, where it shoots its lasers.

Tactics
It has a much longer range than the typical Sniper units. It can also be used to keep units at bay. While this unit is a good ranged attacker which is very difficult to hit, it is very easy to overestimate its capability, as it is surprisingly a very expensive glass cannon unit.
