Game information


"It's a tool with multiple functions. So, you know — multi-tool."
Alyx Vance[src]

The Multi-tool is a device used by Alyx Vance during the events of Half-Life: Alyx. During the period of Half-Life 2 and the Episodes, she instead uses the EMP Tool, a more advanced device, for similar purposes.


The Multi-tool is used to gain unauthorized access to Combine systems through hacking events as well as to reroute the power in unseen wiring systems hidden in the walls of buildings. It can also be used to defuse Tripmines.

Alyx nicknames her Multi-tool the "Alyx", much like how Russell named his Gravity Gloves the "Russells". Russell himself expresses great admiration over Alyx's ability to invent the device, considering this achievement to be enough to guarantee her a job in his future plans of going into mass market production of his Gravity Gloves after the defeat and complete banishment of the Combine from the Earth.

The Multi-tool appears to have been built from parts of a portable cassette recorder.
