BirdcagePC

The RADON and SELENE fleets are about to engage in all-out war in low-Earth orbit.
You are a Pilot of the Radon Fleet, awoken from your Training Stasis by an unexpected emergency call. The unknown caller urges you to destroy your own fleet from within, using your prototype ship — the HALCYON.

To prevent war and escape the Birdcage, you must take down the RADON DAUGHTERS, a Special Unit of the Radon Fleet — and your own Sisters.
