End of Abyss Pulse Gun: Mechanics and the Charged Shot

The Pulse Gun — called the “pulse pistol” in pre-launch press — is Cel’s starting weapon and the backbone of the kit through the entire descent. It never runs out of ammunition, but it’s deliberately not an infinite hose, and its signature charged shot comes with a real cost. Here’s how it actually works in the launch build, and where it sits in the full arsenal.

What is the Pulse Gun?

The workhorse of the arsenal — the gun you’ll lean on from the opening minutes to the final boss. It’s the kit’s baseline: not a pea-shooter to discard, but the default tool around which the Riot Breaker, Security Rifle, and the rest are arranged. Where every other weapon’s ammo is a scavenged resource, the Pulse Gun is always there.

Does the Pulse Gun have unlimited ammo?

Yes and no: you’ll never scavenge or craft ammo for it, but the clip recharges rather than holding infinite rounds. That distinction is the whole design. Fire continuously and the clip runs dry, then recharges on its own. Unlimited ammo means freedom from scavenging, not freedom from trigger discipline — spray blindly and you’ll hit an empty clip exactly when something closes the distance. Paced, deliberate fire is the rhythm the gun rewards, and it suits the game’s survival-horror pacing.

How does the charged shot work?

Hold the fire button and the gun charges a single, powerful shot; release to fire it. It’s the pistol’s heavy-hitting option — the answer when a target deserves more than chip damage: tough single enemies, boss punish windows, opening a fight with a stagger.

Why can’t the gun shoot right after a charged shot?

After firing the charge, the gun briefly cannot shoot at all — a deliberate risk/reward valve on the big hit. That lockout stops the charged shot from becoming spam. If it kills or staggers the target, the downtime costs nothing; if it misses, you’re unarmed for a beat while the facility’s residents keep coming. Every charge is a bet that one heavy hit solves the problem.

When should you charge instead of tapping?

• Tap-fire for general pressure, pacing your clip, and anything you can whittle down while circling it.
• Charge for single targets that deserve a heavy opener, for tough enemies at close range when Riot Breaker shells are too precious to spend, and for reads on a predictable approach.
• Neither, sometimes — crowds are the shotgun’s and grenades’ job, and flares can remove a target from the equation entirely. Tool discipline beats weapon loyalty; see the combat guide.

How does the charged shot pair with dodging?

Build the charge while moving, release, and let a dodge-roll cover the lockout. Standing still to charge hands initiative to the enemy. Charge during safer windows — while repositioning or while an enemy recovers — release, and immediately keep moving so the lockout happens on the move. The unlimited-ammo model is what makes the loop sustainable: you never choose between ammo economy and repositioning.

Can you upgrade the Pulse Gun?

Yes — weapons upgrade at workbenches in safe rooms using materials scavenged from the facility and its monsters. Maxing any single weapon earns the “Power Up” trophy, and the Pulse Gun is the natural first candidate since it’s the weapon you fire most. New players should pair it with the beginner guide and the scanner guide — scanning enemies for behavior data is how you decide whether a target is worth the charged shot’s lockout in the first place.
