Overview
Aegires is a Tier 4 naval support unit that combines respectable bulk, point defense, and a large energy field aura. It can be produced from the naval progression and is notable for being one of the toughest Tier 4 units, with 12,000 health. Its weaponry is centered on point defense rather than direct fire, letting it intercept incoming projectiles while it advances or holds position.
Its defining feature is the energy field, which deals area damage and restores nearby allied blocks and units by a percentage of their maximum health. Because the healing is percentage-based, Aegires is especially effective on high-health targets such as late-tier units, while low-health structures gain comparatively less raw recovery each tick. The field also applies a status effect that reduces enemy fire rate, making Aegires valuable both as a healer and as a front-line disruption unit. It is an expensive unit to field, but its mix of survivability, support, and anti-projectile pressure makes it highly influential in water-heavy battles.
Aegires carries point defense mounts that fire rapidly and can destroy incoming bullets, which helps it survive against enemy turrets and units that rely on projectile damage. Its role is strongest when used to support larger allied forces rather than rushing alone. Since its healing works around it in an area, grouping it with durable units can create a strong advancing formation that is difficult to wear down.
In combat, Aegires is especially useful in long matches and defensive engagements on maps with extensive water. Its field can protect key infrastructure by damaging threats nearby while simultaneously keeping friendly units alive. It is also mobile enough to reposition along water routes, and can be transported over land by an 
Practical notes:
- Plastanium Walls can block the energy field, which is useful for protecting fragile conveyors, power nodes, and other low-durability blocks.
- The field can be stopped with layered defenses; adding Thorium Walls outside the
Plastanium layer helps absorb bullets as well.
- Repair units such as
Poly and
Mega can still be vulnerable if exposed directly to the field, so blocking is important.
- Aegires works best against compact enemy pushes where its status effect and healing can swing a fight over time.
- Stacking multiple Aegires does not scale indefinitely on each other, because same-type healing is reduced between them.
Aegires has changed several times across development. It was added in Build 127, later received speed display changes, item capacity reductions, range adjustments, stronger energy field damage, and multiple balance passes to healing, point defense damage, and firing rate. A later update also added same-type healing reduction to prevent excessive self-sustaining Aegires clusters.
Its name is derived from the Aegires genus of sea slugs, which feed exclusively on sea sponges.
