The Cassette Recorder is a hand-held electrical recording implement that plays back all Cassette varieties. Ironically, it is quite useless without them. When equipping this item on your hotbar, you must first insert a Cassette to have any type of function.
Facepunch added electricity components in the Electric Anniversary update on the 7th of December, 2018, with a considerable amount of additional items coming with the Voice Props DLC patch in July of 2021.
When using the default
Right-Mouse Button, a small rewind animation will play, followed by a 3-second countdown. At the end of 3 seconds (press esc at any time to exit), players may record a voice message up to the length applicable to that cassette type. When using the default
Left-Mouse Button, it will playback whatever is recorded on the inserted cassette.
Only players that have purchased the mentioned DLC may craft these devices, but anyone may use or deploy them. Players must have access to a tier 1 workbench to craft them.
