Everything about the Slime Gun in Slime RNG. Unlock requirements, targeting mechanics, best slime pairings, and DPS optimization strategies.

Contents

The Slime Gun is a player-controlled weapon introduced in the May 2026 update that lets you actively participate in combat instead of relying entirely on AFK auto-battle. By marking enemies, you direct your slimes to focus fire on specific targets — dramatically increasing kill speed and Goop farming efficiency.

What Is the Slime Gun?

The Slime Gun is the first active combat mechanic in Slime RNG. Previously, all combat was passive — your equipped slimes would auto-attack nearby enemies. The Slime Gun changes this by letting you mark specific enemies, causing all your slimes to prioritize that target. This is especially powerful in high-zone farming where enemy HP is high and focused DPS matters.

How to Unlock

  1. 1
    Open the Upgrades Menu
    Click the Upgrades button in your game interface to open the upgrade tree.
  2. 2
    Navigate to the Player Tab
    Switch to the Player section of the Upgrades menu. The Slime Gun upgrade is located here, separate from the roll and enemy upgrade paths.
  3. 3
    Purchase the Slime Gun Upgrade
    Buy the Slime Gun node. Once purchased, the gun becomes permanently available in your loadout.
  4. 4
    Equip and Use
    The Slime Gun appears as a new control. Click on enemies to mark them — your slimes will immediately focus fire on marked targets.

Targeting Mechanics

The Slime Gun uses an auto-lock targeting system. When you click on or near an enemy, the gun locks onto that target and marks it. All your equipped slimes will then prioritize attacking the marked enemy until it is defeated or you mark a new target.

Auto-Lock
Clicking near an enemy auto-locks the gun to that target. You do not need pixel-perfect aim.
group
Team Focus
All equipped slimes redirect their attacks to the marked target, concentrating your full team DPS on one enemy.

Target Switching
Click a different enemy to instantly switch your mark. There is no cooldown between target switches.

Kill Speed Boost
Focused fire kills enemies significantly faster than spread auto-attacks, especially in high-HP zones.

Best Slime Pairings

The Slime Gun benefits most from slimes with high single-target damage. Since all slimes focus on one enemy, you want raw DPS over area-of-effect abilities.

💎 Pro Tip

Pair the Slime Gun with Power Fruits that boost single-target damage (Lightning, Fire). The focused fire from marking + damage multiplier from Power Fruits creates a massive DPS spike on the marked enemy.

DPS Optimization Strategy

priority_high
Mark the Highest HP Enemy First
In zones with mixed enemy types, mark the tankiest enemy first. Your slimes will kill weaker enemies passively while focusing the tough one.
bolt
Combine with Speed Potions
Roll Speed potions do not affect the gun, but attack speed buffs on your slimes make focused fire even deadlier.
zone_person_idle
Use During Active Play Only
The Slime Gun requires manual input. For AFK sessions, your slimes revert to normal auto-attack behavior. Use the gun during active grinding sessions for maximum efficiency.
analytics
Best Zones for Gun Usage
The Slime Gun shines most in Zones 20+ where enemy HP is high enough that focused fire makes a meaningful difference over spread damage.

FAQ

Does the Slime Gun work while AFK?

No. The Slime Gun requires active clicking to mark targets. When you are not actively using it, your slimes attack normally. It is a tool for active play sessions, not AFK farming.

Can I use the Slime Gun in all zones?

Yes. Once unlocked, the Slime Gun works in every zone. However, it provides the most value in high-level zones (20+) where enemies have enough HP that focused fire significantly outperforms spread auto-attacks.

Does the Slime Gun deal its own damage?

The Slime Gun primarily functions as a targeting tool — it marks enemies for your slimes to focus. The gun itself may deal minor damage on hit, but the real value is the team-wide focus fire it enables.
