Airship Fortress

Airship Fortress is a modded stage in Nexed, based on the race track from the Mario Kart series debuting in Mario Kart DS. It was developed by VentureSonic.

History
Airship Fortress is the fourth and final track in the Star Cup in Mario Kart DS, the fifth entry in the Mario Kart series. The race track, with the use of Banzai Bills and Rocky Wrenches, is based off of the airship levels from Super Mario Bros. 3. Airship Fortress would go on to reappear in Mario Kart 7 and Mario Kart Tour.

Layout
Airship Fortress takes place on an airship as it takes off from the fortress, flying through a dark cloudy skyline with several fortress towers passing by. Occasionally, other smaller airships will follow around the central airship. The appearance is ripped straight from its incarnation in Mario Kart DS, with the dark purple sky. However the fortress and airship design has been uplifted to resemble its counterpart from Mario Kart Tour, which already takes inspiration from the mainline Super Mario series.

The collision of the stage is based entirely around the central airship, consisting of a slight slope on the left and an elevated segment on the right. The central spire and the bow spirit of the ship are intangible to the players, but the sail of the ship is a soft platform which the player can jump on. The sail reacts when the player jumps on it, though this is purely aesthetic and serves no noticeable gameplay differences.

Hazards

 * Banzai Bills: With this hazard on, the once cosmetic smaller airships that would fly by are now mounted with Banzai Bill blasters pointed at the ship. When passing by, the airship will fire a Banzai Bill just across the airship. When the Banzai Bill flies over the airship, it becomes an active hitbox that deals repeated explosive damage before sending the opponent far away. The functionality of the Banzai Bills are similar to their appearance in Super Mario Maker 2, in the Super Mario 3D World game style.
 * Rocky Wrenches: With this hazard on, Rocky Wrenches can appear on the two sides of the ship (indicated in red). Rocky Wrenches will pop out from their manholes and throw a wrench out onto the battlefield, which will hurt opponents. Rocky Wrenches can be dealt with by either attacking them or "footstooling" them.

Trivia

 * Mario will arrive in a black Warp Pipe as opposed to a green Warp Pipe on this stage, referencing the pipes in which large cannonballs fire from in Super Mario Bros. 3.
 * Lightning will strike in the background whenever an opponent is KO'd.
