Drone Awareness

More stuff for The Only Certainty.

When the player gets too close to an enemy, the drone goes into a "Suspicious" state where it searches for nearby threats onscreen (namely, you), and this icon appears above it. When the player gets far enough away the icon vanishes and the drone returns to an Unaware state.

Feedback is much appreciated on this. I wanted to keep the communication as pure as possible without too many bells and whistles, but I still wonder if the 'searching' aspect isn't quite clear enough.
