Interphase is a 1989 combination first-person shooter and puzzle video game developed by The Assembly Line and published by Image Works for multiple platforms.

[1] The player, Chad a Dreamer discovers that subliminal messages are being inserted into DreamTracks to persuade consumers to buy certain products[2] and more worryingly, to push certain political viewpoints and pro-government propaganda.

[3] Using a human to computer interface, known as an Interphase[3][4], Chad sets out to destroy a particularly dangerous DreamTrack stored in a high security building.

[5] The action mostly takes place in two modes: a 3D cyberpunk environment and a 2D schematic map where puzzles are encountered.

While viewing the 2D schematic, the action in the 3D world continues, so it's essential that enemy ships have been dispensed with before puzzle-solving can proceed.
