Drivers are bespoke weapon upgrades that can change how a weapon works. The full release contains 50, and the developer says that leveling a particular weapon gives you more opportunities to upgrade it in these ways. That is the confirmed progression relationship; it does not establish one universal unlock level for every Driver. See the release announcement.
Follow the weapon, not a generic level number
- Identify the weapon you are upgrading.
- Raise that weapon's level as opportunities arise during the run.
- Read a Driver's actual change when offered. The purpose is a behavior change rather than assuming every option is a simple stat increase.
- Compare it with your current setup and the problem you are trying to solve.
This is a reading and decision checklist based on the announced system, not a guaranteed sequence of offers. We do not promise that a named Driver appears at a particular level or in a particular order.
Driver, Plugin or meta upgrade?
| Term | Confirmed role | Do not confuse it with |
|---|---|---|
| Driver | Bespoke change to weapon behavior | A universal weapon fusion recipe |
| Plugin | Modification to weapons or player stats | The weapon-level Driver system |
| Meta upgrade | Part of the game's meta progression | A specific Driver unlock requirement |
The store page separately lists 50 Drivers, 62 Plugins and 18 meta upgrades. These counts describe the release's systems; they are not a purchase or unlock order.
If an old guide describes weapon evolutions
A developer response from June discussed Drivers as a planned full-release feature. The later release announcement is the better basis for the shipped system. Neither the word evolution nor comparisons with another survivor game prove that combining two weapons creates a third.
Use a Driver's in-game description to make the immediate choice. If you are looking for a precise list of all Drivers, a best-Driver ranking or a guaranteed unlock threshold, this guide does not claim those have been verified.
