System Shock is a Genshin Impact Challenger: Series VI Achievement that can be obtained by defeating the Algorithm of Semi-Intransient Matrix of Overseer Network in its overclocked, Overloaded state. To do so, you must deplete the boss' HP and wait until it uses a specific skill before defeating it.
How to defeat the Algorithm of Semi-Intransient Matrix of Overseer Network in its overclocked, Overloaded state in Genshin Impact
Start by heading to the boss' location in The Dune of Elusion. Make sure to have an Electro character on your team. This is non-negotiable, as it's impossible to trigger the overclocked, Overloaded state without one.

You must deplete the boss' HP until it's at a low enough level that you can kill it quickly. Make sure not to defeat it at this point. If you have a strong team, try to monitor your off-field damage sources so that you don't accidentally defeat the boss. Once its HP is low enough, wait until it spawns components, pictured above. Attack the components with Electro to remove the core's invincibility.
Once that's done, the boss will slump to the ground, pictured above. You must defeat the boss while it's in this state. If you manage to do so, you'll get the Challenger: Series VI Achievement called System Shock.
