This page summarizes pretty much everything there is to know about Red Faction: Redemption.
The gameplay of Red Faction: Redemption is much like its two predecessors: Red Faction: Armageddon and Red Faction: Guerrilla. The combat system which has been developed from RF:A, and the open world destruction system from RF:G. RF:R brings in a fully exporable and modelled Mars, Moon and Earth, each one tenth of their real scale. Each main area (Mars, Moon and Earth) has its own unique physics and terrain, which have been adjusted to suit real life geometry and gravity.
More information will be available when Red Faction: Redemption is officially released.
