It seems the developer, Paladin Studios, is trying hard to keep the feel of the arcade classic intact while still giving it a more modern feel. They even brought back “Twin Mode” which allows players to double their firepower.
Derek De Geus, CEO of Paladin Studios says:
Get ready for some good old space bug squishing action when GALAGA WARS releases. It should be available on all mobile platforms soon.
