Warhammer Survivors Lasgun Evolution Guide

Learn how to trigger the Lasgun evolution into the Meltagun in Warhammer Survivors, including level stats, unlock requirements, and Gauntlet pairing.

In Warhammer Survivors, the Lasgun serves as a foundational ranged weapon for Astra Militarum-themed builds. The Warhammer Survivors Lasgun evolution allows players to transform this reliable infantry rifle into the high-damage Meltagun by reaching level 8 and holding the Gauntlet passive. This evolution significantly alters the weapon's performance, replacing the standard las bolts with short-range, high-intensity thermal blasts.

How to Evolve the Lasgun into the Meltagun

Evolving the Lasgun is a multi-step process that requires specific inventory management during a run. Unlike standard level-ups, an evolution completely replaces the base weapon with a superior version while retaining any relevant passive bonuses.

To trigger the evolution, you must meet the following criteria:

  1. Max Level: Upgrade the Lasgun to Level 8.
  2. Passive Requirement: Obtain the Gauntlet passive item. The Gauntlet can be at any level; it does not need to be maxed out to facilitate the evolution.
  3. Evolution Chest: Once the requirements are met, defeat a mini-boss or boss to spawn a chest. Opening a chest that offers an evolution will replace the Lasgun with the Meltagun.

The Meltagun is considered a significant upgrade, though players should note that the Lasgun's specific mechanic—gaining additional troopers to fire alongside the player—is replaced by the Meltagun's unique firing profile.

Lasgun Stats and Level Progression

The Lasgun is characterized by its "additional trooper" mechanic. As you level the weapon, you don't just increase its damage; you effectively increase your squad size, with additional troopers appearing to fire their own lasguns at the nearest enemies.

Note that the Lasgun features a damage fall-off mechanic: the further a las bolt travels before hitting a target, the less damage it deals.

How to Unlock the Lasgun

The Lasgun is not available to all characters immediately. To unlock it for general use in your weapon pool, you must complete a specific objective within the Warhammer 40,000 setting of the game.

  • Requirement 1: You must first find and rescue the hidden character located on the Imperial Bastion map.
  • Requirement 2: Once the character is rescued, you must reach Level 6 with the Lasgun during a single run.

Completing these steps fulfills the "Objective (40K)" and permanently adds the Lasgun to the available loot pool for future attempts.

Starting Characters and Lore

Trooper Bartosz Kozlowski is the primary character that starts each run with the Lasgun equipped. As an Astra Militarum soldier, his kit is designed to maximize the effectiveness of standard-issue Imperial wargear.

According to the in-game documentation, the Lasgun is the favored weapon of the Astra Militarum due to its extreme reliability. While it lacks the sheer stopping power of the kinetic weapons used by the Adeptus Astartes (such as the Boltgun) or the devastating impact of a Chainsword, its ease of maintenance and high ammo capacity make it the backbone of the Emperor's reach in the galaxy.

When evolved into the Meltagun, the weapon shifts from a reliable mid-range tool to a specialized tank-busting instrument, capable of melting through the toughest armor at the cost of the Lasgun's superior range and squad-fire capabilities.
