You have an AP sensor that will buzz when you're near an enemy but doesn't tell you where exactly they are; you have a
motion detector that sweeps round in a
circle around you highlighting pinpoints of movement, but is no use
against a stationary enemy; and you have a sonar that you can use to ping out a pulse and detect enemy object locations (though potentially be found out from the noise).
The inputs might be simpler than Street Fighter's mess of quarter
circles and charge
motions, but you'll still need to memorise them, and get your timing down to stand a chance
against real opponents.
