The Z-44 Plastique™ is an key item found in System Shock.

This high-energy explosive is a package containing focused charge designed to prevent theft of technologically sensitive corporate mining assets of the TriOptimum Corporation. Explosive charges are piggy-backed onto high voltage electrical systems such as satellite communications equipment, and then remotely triggered by radio signals. These explosives are activated by high amperage.

Greg MacLeod managed to gather all Plastique of Citadel Station to hide them from SHODAN's forces in the Storage Level. Most of this was later stolen by the robots and kept in a secured Storage Room 1.

They were used by the Hacker to destroy the Antenna Relays and prevent SHODAN uploading into Earth's network.


To arm the Plastique, select a charge from the GENERAL inventory panel. Use the charge on an external object (double-left-click on the target). The Plastique will detonate after exactly 10 seconds. If you stand too close to the explosion, you’re likely to blow yourself up, even with powerful shields.

If the player drops all of the Plastique (or at least enough that not all the remaining Antenna Relays can be destroyed) into an area that is later rendered inaccessible, the game cannot be progressed. This would be incredibly unlikely for the player to do absent-mindedly. It is recommended for the player to leave four empty General inventory slots before beginning the quest involving Plastique explosives.
