Duckside has crafting, base-building, PvP, PvE, and, since you're a duck, it has flying too. Precision flight controls allow you to maneuver through the air both in combat and just to scout, while you'll also upgrade your weapons (read: guns) along with your bases to defend against enemy raids on servers that support up to 50 fowl players.
