Zero Company Unstoppable

What it does

Costs 1 Action Point and grants 2 stacks of Retaliation. Each incoming attack burns a stack to counterattack the attacker. Ranks raise the counterattack damage to a maximum of +4, and the final rank allows it to be cast on an ally rather than the Heavy, where a guide also reports a ceiling of 4 Retaliation stacks.

The ladder carries its own evidence, and it is weaker than the ability’s. EA published what each ability does at its first rank; guide writers read the rest off the shipped game’s Focus Tree. Nothing here has been reproduced by this site, and no source has published what any rank costs.

The offensive half of the tank kit, and it only pays out when the enemy actually attacks the Heavy — which is what the Intimidating Posture taunt and Bulwark exist to arrange. Used without them it is dead weight. The final rank's ally targeting is the interesting one: put it on whoever is about to be focused rather than on the Operator already built to survive it. One Action Point is the figure that turns this into a turn rather than a habit. A Heavy has three, Bulwark is once per turn, and Intimidating Posture is free — so the tank's opening turn is a taunt, this, and whatever a single point still buys. The reported four-stack ceiling at maximum rank is the other half of that sum: two stacks a cast against a cap of four means a second cast is worth a point on a turn the first two stacks have already been spent, and worth nothing on a turn they have not.

• STAR WARS Zero Company™ Specializations and Weapon Classes

  EA Help · Tier 1 — Official · accessed 30 August 2026

  Supports: "Every Specialization includes a unique set of abilities" and "Each Specialization includes three types of abilities" — Ultimate ("a Specialization's most powerful ability"), Standard ("an active ability you can use during combat") and Passive ("always-active abilities... without needing to be activated"). Note that this is three *types*, not three abilities: nothing on the page says how many Passives a Specialization has, and the per-Specialization ability lists sit behind collapsed accordions that are not in the retrieved text. "Most abilities cost Action Points (AP) to use... These special abilities cost Advantage instead of AP. Advantage is a shared resource that your squad can earn as a battle progresses." On authored characters: "Authored Operators have assigned Talents that you can't change, and some Authored Operators have Specializations that you can't change." On dual specialization: "Later in the game, you'll be able to choose an additional specialization for your Operators." Combat stat definitions — Weapon Damage "The amount of damage dealt by the weapon when attacking"; Critical Hit Damage "The additional damage applied when an attack Critically Strikes"; Critical Chance "The chance the weapon has of critically striking a target for extra damage"; Range "The optimal weapon range for combat. Attacking outside of this range incurs a Strike Penalty." All four Weapon Class panels, read on 2026-08-30 by expanding the page's accordions in a browser — combat stats as printed: Blaster Rifle "Weapon Damage 10, Critical Hit Damage +6, Critical Chance 5%, Range Medium"; Repeater "8, +4, 5%, Medium"; Blaster Pistol "6, +4, 5%, Short"; Longarm Blaster "12, +12, 5%, Long". **All four are 5%.** Action types and costs, verbatim: the Blaster Rifle is fired "once per turn as a Fast Weapon using 1 x AP" with "additional shots in the same turn cost 2 x AP"; the Blaster Pistol "is a Fast Action weapon, which means each shot costs 1 x AP"; the Longarm Blaster "is a Slow Action weapon, which means each shot costs 2 x AP"; and the Repeater "deals significantly more damage if you invest additional AP while firing it. The more AP you spend, the more Rapid Fire Damage it deals", with no fixed figure given. The eight per-Specialization panels expand too, but their ability lists are **inside screenshots** rather than in text — the Assault panel's image reads "SWEEPING SALVO / ULTIMATE / Unleash aggressive blaster fire that deals damage and Disorients all enemies within a large cone", "BULL RUSH / STANDARD / Charge into an enemy, dealing Melee Damage and Pushing it backwards", "FLEET OF FOOT / PASSIVE / Increases this Operator's First Movement by 1.0m", "STRIKE THE FLANKS / PASSIVE / This Operator gains a +20% Critical Chance bonus against Exposed enemies". An image caption on the same page names a "Final Action attack". Page header "Updated 2 days ago", retrieved 2026-08-30.

• Star Wars Zero Company Heavy Class Guide: Abilities and Builds

  VULKK · Tier 3 — Retail review · accessed 10 September 2026

  Supports: Published 9 September 2026, the same day as Patch 1.1, and **it does not state which build it was written against** — which is why nothing taken from it is filed as 1.1 behaviour. Bulwark reported at "up to 24m cast range" with an "8m area" and its Defense bonus "scaling from +2 to +6": all three reproduce `retail-htm-heavy` exactly, and are the first corroboration that ladder has had. Unstoppable "costs 1 AP", "starts with 2 Retaliation stacks", and at maximum rank "can be applied to allies" and permits "up to 4 Retaliation stacks" — the AP cost and the four-stack ceiling appear on no other source read in this pass. Impact Underlay "reduces incoming melee damage by 50%", the first published effect for any Underlay outside the Reinforced line. On Intimidating Posture: its Taunt "also triggers from blaster-based AoE attacks and from Assist Attacks", and the guide draws the conclusion itself — a Heavy with Sweeping Salvo "can Taunt every enemy the cone hits". **Checked for and absent**: any Advantage cost for Bulwark, which remains unpublished everywhere.
