"Mass Effect: Infiltrator" is an iOS-only (for now) 3rd-person cover-based shooter, developed by Iron Monkey (who developed the excellent iOS version of "Dead Space").
It is set around the time of "Mass Effect 3", and your progress in "Infiltrator" will increase your "Galactic Readiness" in ME3 via the "Galaxy at War" system.
Iron Monkey worked closely with BioWare's Casey Hudson and Mac Walters to keep it true to ME.
