In ARC Raiders, the extraction shooter from Embark Studios, survival is an ongoing math problem. Every deployment forces you to balance risk, inventory weight, and fire power. While primary weapons like the Anvil or the Tempest get most of the spotlight, veteran Raiders know that utility wins fights. Among the tactical gear available, one Rare Grenade constantly stands out as a genuine fight-altering tool: the Showstopper.

This isn't your standard fragmentation explosive. The Showstopper is a specialized tactical item engineered to emit a massive, EMP-like electrical blast upon detonation. Whether you are pinned down by a squad of aggressive rival human Raiders or being hunted by relentless mechanical ARC machines, this small device can single-handedly halt the chaos and swing the tactical momentum back in your favor.

The Hard Numbers: Key Stats & Mechanics

To truly understand why the Showstopper earns its name, you have to look at its technical breakdown. It doesn't rely on raw damage; instead, it manipulates time and space on the battlefield through precise crowd-control metrics:

• Weight & Value: Space is money in your rig. The Showstopper weighs a modest 0.4 kg, making it easy to stack. If you manage to extract with extra units or decide to clear out your stash, recycling a single Showstopper yields a hefty 2,100 Scrap/Materials.

• The Stun Window: The crowd control duration shifts drastically depending on your target. When caught in the blast radius, mechanical ARC units are completely paralyzed for a massive 7 seconds. Human Raiders, on the other hand, suffer a brutal 2-second hard stun—more than enough time to disrupt their aim or stop a sprint.

• Blast Radius & Delay: The grenade boasts a generous 6-meter blast radius. If thrown traditionally, it operates on a standard 3.5-second fuse delay.

• Smart Detonation Mechanics: You don't always have to wait out the 3.5-second timer. The Showstopper features two built-in instant-detonation overrides. First, scoring a direct impact on an enemy triggers an immediate explosion. Second, it utilizes an automatic air-burst/proximity fuse. If the grenade travels or bounces within a 2-meter radius of any active hostile, it detonates instantly mid-air, leaving zero time for the target to roll away.

Tactical Breakdown: How to Maximize the Shock Value

The difference between a rookie throwing a Showstopper and a veteran using one comes down to positioning and target priority.

1. Dominating the PvP Meta

In high-stakes player-versus-player encounters, 2 seconds is an eternity. When an enemy Raider pushes your cover, landing a proximity Showstopper freezes them in place for exactly 2.0 seconds. Because they cannot return fire or maneuver, this brief window allows you to line up clean, uncontested headshots using high-caliber weapons like the Anvil pistol. It is also an exceptional tool for halting a fleeing rival who is carrying high-tier loot toward an extraction point.

2. Exploiting Mid-Tier Vulnerabilities

The electrical blast is a death sentence for smaller, agile ARC units. Airborne threats like Hornets and Wasps are completely grounded by the blast, dropping straight out of the sky for easy follow-up damage. Furthermore, it is incredibly effective against Rocketeers. By aiming the grenade near their exposed side thrusters, the shockwave temporarily disables their flight stability, flipping the machines over and exposing their weak underbellies.

3. Understanding Armored Resistance

However, the Showstopper isn't an omnipotent panic button. Massive, end-game ARC threats like Bastions or Bombardiers are reinforced with heavy black plating. This dark armor heavily absorbs or completely shrugs off the EMP effect. Throwing a single grenade at a full-health Bastion will do little to halt its main turret rotation, though it may occasionally lock down its leg movement temporarily.

4. The 1,000-Damage "One-Shot" Execution

To bypass the limitations on larger targets, advanced squads utilize the "One-Shot" combo. By chaining two Showstoppers back-to-back, players can securely lock down a vulnerable, medium-sized target for a continuous 14 seconds. While the target is immobilized, a Raider can safely sprint into point-blank range, plant a heavy Deadline Mine directly beneath the machine, and back away. The resulting explosion deals a devastating 1,000 damage, instantly vaporizing most mid-tier threats without firing a single bullet.

Securing the Formula: How to Unlock the Showstopper

Because the Showstopper is a vital piece of utility for high-risk runs, relying on the few grenades you find in random crates isn't a sustainable strategy. You need to unlock the permanent crafting recipe at your Workshop so you can manufacture them before dropping topside.

To do this, you must track down the specific arc raiders blueprints for the device. If you are struggling with the random loot pools, specialized trading communities like U4N offer reliable options to acquire rare blueprints and progression items directly, saving you from dozens of hours of brutal RNG grinding.

In standard gameplay, securing the blueprint requires a mix of luck and trader progression in Speranza. It can occasionally drop as a rare, random piece of salvaged loot from high-tier military containers topside. Alternatively, you can unlock it reliably by completing late-game trader questlines—specifically through mid-to-late progression missions handed out by Shani and Apollo. Once the blueprint is safely extracted and turned in, you can craft the grenade at will using standard electrical components, voltage converters, and salvaged Hornet parts, ensuring your squad always drops into the Rust Belt with a pocket-sized EMP ready to go.
