Face of Mankind was a first and third-person massively multiplayer online action role playing game (MMOARPG) set in a futuristic persistent world.

Players interact with each other in a freeform universe, consisting in a series of locations spread across various planets.

Major roleplaying-based storylines, purely optional, are started and run by Duplex staff.

Players in a position of power may also affect gameplay by setting a faction's agenda, creating long-term political, economic, or military goals, which are broken up into missions handed down through a faction's hierarchy in the form of player generated and driven missions.

[4] New characters may choose to go through the in-game tutorial and learn the basics of the game, such as movement, combat, and other important concepts.

New players are considered Trainees until they finish enough of these starter objectives to get 10,000 experience and be automatically promoted to Rank 1.
