1.Summary 
Still throwing grenades one by one in ARC Raiders? The Heavy Fuse Grenade trial isn’t about aim—it’s about herding. Group enemies together, use your ARC Raiders Items efficiently, and a single grenade can deal up to 14,400 damage, easily breaking the 10K requirement. This guide will help turn grenade spam into smart demolition.

【Tip 1】Step One: Lock the Door, Gas the Entrance – Build a "Slaughterhouse" for Shredders  
Don't throw yet! First, seal the double doors with Barricades + Door Blockers, then drop Gas Mines at the entrance – not for the monsters, but to keep other players away.  
Key point: Leave a little room to move. If you seal it too tight, the AI glitches and scatters. A perfectly herded pack needs space to stay together.

【Tip 2】Step Two: Three "Sheep-Herding" Routes – Make the Monsters Follow You  
Recommended order: Medical Research (most reliable) > Cultural Archives (backup) > Business Center (last resort).  
Equip an Anvil with Extended Barrel. Do NOT shoot – just body-pull aggro and lead the Shredders.  
Key point: Dodge small enemies blocking the path; if a Shredder gets stuck on stairs, reposition. Pop Adrenaline for speed, carry a Defibrillator for mistakes, and equip the Survivor Augment.

【Tip 3】Step Three: One Grenade to Rule Them All – Explosive Damage 
Once you've gathered at least 8 Shredders, find a safe spot and aim your grenade dead center of the pack.  
In testing, 9 Shredders hit together dealt 14,400 damage – double the trial requirement.  
Key point: If the grenade bounces off the floor, you lose most of the damage. And always check for other players before you throw.

【Tip 4】Step Four: Stay Alive – Plan Your Escape Early 
Herding takes time and draws attention. Other players can ruin your run at any moment.  
Main extract: Lobby Metro. Backup: carry a Hatch Key.  
Remember: Spending 10 minutes setting up a perfect trap only to die on the way out makes you the biggest sucker in the raid.
