Warhammer Survivors Upgrades: How to Unlock All Evolutions

In Warhammer Survivors, upgrades primarily take the form of "Evolutions," which transform standard weapons into devastating tools of destruction. To upgrade a weapon into its evolved form, you must reach the maximum level with that weapon, possess its corresponding passive item, and then collect a chest dropped by a mini-boss. Unlocking all 21 available evolutions in the 40K universe grants a permanent reward known as Archeotech.

The Evolution Process

Upgrading your arsenal is not as simple as spending currency; it requires specific gameplay steps during a run. The mechanic is similar to other "survivor-like" titles where synergy between weapons and passives is key.

Step-by-Step Upgrading

1. Max Level Weapon: You must upgrade your base weapon to its maximum level during your current run.
2. Acquire the Passive: You must hold the specific passive item that pairs with your weapon. For most evolutions, simply owning the passive is enough, though some high-tier upgrades require the passive to be maxed out as well.
3. Defeat a Mini-Boss: Look for enemies marked with a green outline. These are mini-bosses that drop chests upon death.
4. Open the Chest: If you meet the weapon and passive requirements, opening the chest will trigger the evolution.

Once an evolution is triggered for the first time, the game will helpfully mark matching passives on the level-up screen in all future runs, making it easier to track your build path.

How to Unlock the Armoury

To keep track of every recipe and upgrade path, players must unlock the Armoury. This menu serves as a reference for all discovered evolution combinations.

To unlock the Armoury, you must find the Munitorum Dataslate relic. This item is located on the Gallowdark map and is represented by a question mark icon on your mini-map. Once collected, you can view the recipes for any evolutions you have previously discovered at any time from the main menu.

Evolution Recipes and Combos

There are 21 evolutions to discover in the Warhammer 40K universe of the game. Some of these are "Shared Evolutions" that also appear in the Age of Sigmar content.

Note: The Heavy Flamer is highly effective when further paired with the Bandolier, which increases reload speed for a constant stream of fire.

Best Early-Game Upgrades

While some weapons have difficult unlock criteria—such as killing 100,000 enemies in a single run or collecting paint pots to recruit characters—there are several powerful upgrades available early in the game to help you survive longer.

Heavy Flamer (Crowd Control)

The Heavy Flamer is considered the premier tool for managing late-stage hordes. Because players start with the Flamer and Glue available, it is often the first evolution a player can reliably build. When combined with a Bandolier, it creates an unending stream of Promethium, making it much easier to handle mini-bosses and dense crowds.

Deathstrike Missile (Screen Clear)

To get this upgrade, you must first survive 20 minutes with any character to unlock the Storm Eagle Rocket. When paired with the White Dwarf passive, it evolves into the Deathstrike Missile. This weapon is unique because it wipes out all enemies currently on the screen and acts as a magnet, summoning every experience gem on the stage directly to your character. Since the White Dwarf also boosts XP gain, this combo allows for rapid leveling.

Mordant Earth (Utility and Slow)

Using the Nuln Oil and Hourglass (both base unlocks), you can create Mordant Earth. This evolution creates large puddles of tar that damage and slow down enemies. It is particularly effective when paired with the Tape Measure passive, which increases the size of the tar puddles, allowing you to coat large portions of the arena in slowing goop.

Completion Rewards

Hunting down every upgrade is more than just a completionist goal. If you successfully unlock all 21 evolutions in the 40K universe, you are rewarded with Archeotech. This special in-game reward guarantees a base weapon at the start of runs, providing a significant advantage for tackling Extremis boss fights and higher difficulty tiers.
