DARTWING

Toy drones with foam darts, in the back yard, at toy scale — the pond is an ocean, the garden is a jungle and the swing set is a fortress. Two squadrons of four. A hit costs you a fifth of your battery; run it out and you sputter down onto the grass and come straight back, so nobody is ever out.
Hold R for the throttle — let go and you stop and hover, and a slow drone turns much tighter than a fast one, so easing off is how you come round inside somebody. Hold A to hose darts, B to boost, and L1 or L2 to barrel roll left or right — which deflects darts outright, and is the whole defensive game. Hover over your own charging pad to fill the battery back up.
Grab the Triple Dart, the Foam Ball and the Bubble Shield — and watch for the sprinklers, the wind and the bird.

Pads: left stick steers  ·  R1/R2 throttle  ·  A fire  ·  B boost  ·  L1/L2 barrel roll left and right  ·  X foam ball  ·  Start pause

Touch: the d-pad steers and GO is the throttle.
The nose levels itself the moment you let go, so there is nothing to recover from. Invert Y is in OPTIONS, per seat.
