Siege Casing I, II, and III Respectively


The Siege Casing is an advanced special for Projectile Weapons developed by the Xeno Division. It is only able to be equipped on the Exterminator Destroyer and is meant for sniping bases.

Strategy and Setup


Being a very advanced special, it is one of the best specials currently in the game as of now. It is a special mostly suited to sniping bases with Destroyers and tanking with its HP and resistance.

Being a sniping special it gives extra module damage and projectile speed which are very crucial stats during a sniping attack. Even when not in a sniping attack the projectile speed will better ensure a hit on the enemy than without it.

But it doesn't stop there, It also gives a projectile resistance of almost 40% maximum. This can make destroyers even more tanky against turrets like the Storm Driver Turret. This greatly improves the survivabilty of your destroyers once the decoys fall.

On top of all that, it also adds extra health to the destroyer to further improve its ability to tank damage from bases or normal fleets which helps even more. It also adds very little weight.


However, the health also means added repair time. Which means if the destroyers are destroyed it has a higher repair time than without the special. It is however not a really major disadvantage.

The main problem is that people rarely use the sniping strategy anymore and switched to rushing which is faster, easier, more profitable, and less susceptible to intercepting.

It also is only for the Exterminator Destroyer, making it useless without the hull.



  • This is the first Projectile special since Electric Rails, and the first to have a Xeno Variant.
  • This special has to most buffs and debuffs out of any special so far
  • The special is more suited for sniping, but alot of people prefer to rush making it less common than if it was 1 year ago.
