The Heavy Fuze Grenade is a throwable explosive in Arc Raiders that detonates after a fixed delay instead of exploding on impact. It has a 3-second fuse, a 7.5-meter blast radius, and deals 80 explosive damage at full effect.

In general, this grenade is designed for planned explosions rather than quick reactions. Most players treat it as a tool for area control, flushing enemies out of cover, or setting traps, not as an emergency panic button.

You unlock or craft it at Explosives Station II, and it requires Explosive Compound and Canisters. It is craftable, usable in normal gameplay, and can be carried like other grenades.

How Does the 3-Second Fuse Work in Practice?

The 3-second fuse starts as soon as the grenade leaves your hand. There is no cooking mechanic, so you cannot shorten the timer. Once thrown, the timing is fixed.

In practice, this means:

• You must throw it ahead of enemy movement

• You need to predict where players or enemies will be

• Poor timing usually means wasted grenades

Most players miss their first few throws with this grenade. The delay feels long at first, especially if you are used to instant explosions or impact grenades in other games.

In general, the Heavy Fuze Grenade works best when enemies are:

• Looting

• Healing

• Fighting something else

• Forced to stay behind cover

If players are sprinting in open ground, the grenade is usually easy to avoid.

How Much Damage Does It Really Do?

On paper, the grenade deals 80 damage. In practice, the actual damage depends on distance from the explosion.

Most players experience it like this:

• Very close: heavy damage, sometimes lethal if already wounded

• Mid-range: solid chip damage

• Edge of radius: light damage or just pressure

It will not reliably one-shot a full-health player on its own. Usually, it is used to set up a fight, not finish one.

Against NPC enemies, it performs better because many AI units do not dodge as effectively. Groups of smaller enemies can be cleared or heavily damaged if they are clustered.

What Is the Blast Radius and Why Does It Matter?

The 7.5-meter radius is fairly large for Arc Raiders. In enclosed spaces, this feels much bigger than it sounds.

In general:

• Indoors: very effective

• Tight corridors: strong zoning tool

• Open areas: less reliable

Most players use it to:

• Clear rooms

• Deny stairwells

• Control choke points

• Force enemies to reposition

Because the grenade does not explode instantly, the radius works more as psychological pressure than raw damage. Players usually move away as soon as they hear it land.

How Do Players Usually Use the Heavy Fuze Grenade?

Experienced players tend to use this grenade in predictable patterns.

Area Denial

Throwing it into doorways, hallways, or narrow paths forces enemies to wait or move. Even if no one takes damage, it buys time.

Flushing Enemies Out of Cover

If someone is hiding behind an object, most players will move rather than tank the explosion. This creates openings for gunfire.

Third-Party Fights

When two groups are already fighting, players are less aware of grenade timing. This is one of the best moments to use it.

Trap Setups

Some players throw the grenade where they expect enemies to move next rather than where they are now.

In general, the grenade rewards patience and prediction more than fast reflexes.

When Is the Heavy Fuze Grenade a Bad Choice?

Despite its strengths, this grenade is not always the right tool.

It usually performs poorly when:

• Enemies are highly mobile

• Fights happen in wide open terrain

• You need immediate damage

• You are reacting under pressure

Most players do not rely on it as their only explosive. It is often paired with weapons that can capitalize on forced movement.

If you throw it late or panic-throw, it often explodes harmlessly behind fleeing targets.

Crafting Cost and Resource Value

To craft one Heavy Fuze Grenade, you need:

• 1x Explosive Compound

• 2x Canisters

The station requirement is Explosives Station II, which means early players may not have access right away.

From a resource perspective, the grenade is not cheap. In general, players only craft them when:

• They expect PvP encounters

• They are planning contested runs

• They have excess crafting materials

Because the grenade costs more than lighter throwables, most players do not spam it. It is usually saved for meaningful encounters.

Is It Worth Carrying Into a Raid?

Whether it is worth bringing depends on playstyle.

Most players who benefit from it are:

• Methodical

• Position-focused

• Comfortable predicting movement

If you prefer fast pushes or reactive combat, this grenade can feel slow and awkward.

In general:

• Solo players use it cautiously

• Squad players get more value from it

• Defensive players benefit the most

It shines when coordination or planning is involved.

Common Mistakes New Players Make

Many players struggle with the Heavy Fuze Grenade at first.

Common mistakes include:

• Throwing directly at moving targets

• Expecting instant damage

• Using it in open fields

• Forgetting the fuse timing under stress

Most experienced players recommend practicing throws in low-risk situations to learn the delay and bounce behavior.

Once the timing becomes intuitive, the grenade feels much more consistent.

How It Fits Into the Overall Explosive Meta

In the broader explosive lineup of Arc Raiders, the Heavy Fuze Grenade fills a specific niche.

In general:

• It is not a burst damage tool

• It is not a panic defense option

• It is a positioning and control explosive

Most players view it as situational but reliable when used correctly. It does not replace faster grenades, but it complements them.

If you understand how players move, hide, and retreat, this grenade becomes much stronger.

Final Thoughts From a Player Perspective

The Heavy Fuze Grenade is a thinking player’s explosive. It rewards awareness, patience, and prediction rather than speed.

Most players who dislike it simply expect it to behave like an impact grenade. Once you accept the delay and plan around it, the grenade becomes a useful tool for shaping fights instead of ending them outright.

In general, it is not mandatory, but in the right hands and situations, it can quietly swing engagements without drawing attention to itself.
