Communicator

In Strife, the Communicator, usually referred to in-game as the com unit, is an item obtained from Rowan after completing his quest to assassinate Beldin. With this, the player can receive incoming messages from BlackBird and other information.

In the demo version, the com unit is instead found in Harris's stash inside the tavern if the player correctly deduces the man's treachery and kills him instead of accepting his promise of "gold and glory" by taking the key to the governor's office.

Technical
The item gives the player a power-up status, similar to shadow armor or an environmental suit. This permanent power-up status is checked for by linedefs with actions which start voice sound effects.
