Mechanoid cluster

Royalty added a new type of hostile event - the "Mechanoid Cluster". These may be associated with quests, or can spawn in place of a human raid. During this event, a fleet of drop pods will land and deploy mechanoids, walls, turrets, and assorted buildings. These mechanoids will initially be dormant, and are eventually awakened by the player attacking, a Proximity activator being tripped, or a Count-down activator finishing its count down.

Building types

Mech drop beacon	?	100	A mechanoid reinforcement drop beacon. When activated, it calls in a group of mechs to land in drop pods nearby.	Calls mechanoid reinforcements in a local area.	1x1	No
Proximity activator		100	A proximity alarm for dormant mechanoids. If it detects a human-like threat nearby, it will awaken any nearby dormant mechanoids or structures.	Activates any nearby sleeping mechanoids.	1x1	No
Count-down activator		100	A timed mechanoid activation unit. After counting down, it will wake nearby dormant mechanoids and structures.	Activates any nearby sleeping mechanoids.	1x1	No
Bullet shield		200	A shielding device which projects a momentum repulsor field. Shots can go out, but not in. This one is tuned to low angles, so it will block ground-level projectiles like bullets. The unit can be temporarily disabled by EMP attacks, either by shocking the projector unit itself, or using EMP munitions on the shield.	Blocks pawn's projectiles from firearms.	1x1	No
Mortar shield		200	A shielding device which projects a momentum repulsor field. Shots can go out, but not in. This one is tuned to high angles, so it will block mortar rounds. The unit can be temporarily disabled by EMP attacks, either by shocking the projector unit itself, or using EMP munitions on the shield.	Blocks mortar rounds.	1x1	No
Gloomlight	?	50	A self-powered mechanoid light. Gloomlights can be deconstructed to yield valuable resources, or used as lights - but only if they are captured intact. The internal micro power cell will flame out and ruin the materials if the unit takes too much damage.	Emits light	1x1	No
Unstable power cell		200	A mechanoid power generation unit. The vanometric power core will run forever, extracting energy from quantum foam fluctuations. An internal amplifier system makes it unstable. If damaged, the unit will generate a massive explosion.\n\nSome brave humans steal these from mechanoids for their own use as power plants or defensive bombs. However, an unintentional detonation can be devastating.	Provides 400W of power	1x1	No

Tactics

Mech Clusters are best dealt with an extreme range, to avoid placing your colonists in unnecessary harm.

Colony Weapons

Mortars

For Mech Cluster without a Mortar Shield, mortars are obviously the best way to deal with them as they present many foes that stay in a small, confined area. Prolonged shelling can easily destroy mech clusters and weaken the mobile mechanoids before triggering them to attack your colony, where you can take advantage of your base defenses.

For Mech Clusters with Mortar Shields, you can either try to destroy the shields first with snipers or simply overpower the shield. Each mortar shield is temporarily deactivated for a few seconds when they block a mortar shell. As such, a battery of 4-8 mortars timed to all fire at once can easily penetrate the shield with most of its shells. Mixing a few EMP shells in can also help disable the Mortar Shield, allowing successive salvos to ignore and hopefully destroy the shield before it can come back online.

Orbital Bombardment/Beam Targeter

Another easy way to destroy a Mech Cluster is to save your Orbital bombardment targeter or Orbital power beam targeter for them. These are quite rare as they're found only via quest rewards and ancient dangers. However the damage they rain down can easily destroy even a double or triple strength mech cluster, leaving only Centipedes as survivors to assault your base.

Sniper Rifles/Rocket Launchers

The Sniper rifle, Triple rocket launcher, and Doomsday rocket launcher are all long range weapons. The two rocket launchers also do extra damage vs buildings. Using these three weapons with a coordinated first salvo from prepared forward positions (a few walls built near the front for cover), you can inflict severe damage upon Mech Clusters as soon as they wake up. Opening volleys should focus on taking out any defending long-range mechanoids (Lancers/Pikemen) and the Auto-Inferno Turret. While the Mini-Slugger Turret and Auto Charge Blaster Turret both have high range, the former has weak shots and the latter is wildly inaccurate at range, which means your colonists incur minimum risk from them by attacking from long range and behind cover.

Depending on the damage you inflict from opening salvos and the mechanoids behavior, you may have to decide between withdrawing to your base or mounting a shootout from your forward positions.

IEDs

For a Mech Cluster without any proximity activators, 1 explosive IED can take out any turret or small building. 1 EMP IED has a bigger area of effect than a EMP mortar shell. IEDs can be daisy chained to cover a greater area. The IED can be set off with a targeted attack such as a sniper rifle, a mortar volley, or by waiting for an activation timer to count to 0.

Care must be taken to keep colonists 2 squares away from units or buildings while constructing the IED to prevent the cluster from waking up.

Grenades

EMP grenades can disable both mechanoids and mech cluster buildings. Meanwhile Fragmentation grenades inflict high damage vs buildings and can destroy any mech cluster turret with one hit. Thus a grenadier team, taking advantage of cover from steel walls that often come down with mech clusters, can inflict significant damage if the mobile mechanoids can be lured away and defeated first.

Alternatively, a colonist with the Skip and Invisibility Psycasts can move into a Mech Cluster, use grenades to quickly destroy priority targets, then use Skip to withdraw as soon as the Invisibility wears off.
