All worlds redrawn with smooth coastlines and shore gradients, grain and mottle, dirtier war-torn palettes, irregular stains, war damage and contact shadows.
Per-world details: layered clouds over hazed ground, storm swell, whitecaps and wreckage, canyon strata, dry riverbeds and mesas, swamp reeds, logs and shacks, ruined street grids and rubble, sakura petals, paths, lanterns and shrines, crystal clusters, oilfield derricks, tank farms and flares, crash furrows, graveyard hulks and buoys, jungle clearings.
Ocean depth, swell and caustics, arctic sastrugi and outposts, volcano lava crust with glowing veins and ash, desert dunes, convoys and an oasis camp, farmland hedgerows, orchards and herds, a clean void grid, and a bombed Gunship Alley.
Trees redrawn: leaf-clump canopies, tiered snow pines, fronded palms and gnarled dead trees.
WW2 trucks, jeeps, staff cars and half-tracks on the roads per biome, with a matching burnt truck wreck.
Ambient WW2 freighters, destroyer escorts and landing craft at sea with speed-scaled wakes, and matching wrecks.
The storm and oilfield worlds lose their soft blobs and sheen; the desert wadi bands are softer and sandier.
Enemy planes get a thin dark outline so they stand out from the terrain.
Your plane (with its hardware) and bosses are drawn above explosions and smoke, and the big screen flash no longer dims them.
Bosses get a dark silhouette rim and a capped hit flash so they stay readable.
Interface
The plane card is decluttered: the decorative "patched" and "repaired" stamps are gone.
Hub toasts sit under the tab bar in portrait or over the hangar scene in landscape, instead of covering the header.
Achievement pop-ups no longer cover the top bar.
Performance
Faster startup: the 3D world map loads only when the hub idles or you open the map.
The main menu drops to a low-power mode after 15 seconds without input, which saves battery (any touch wakes it).
Less work per frame in the hangar, camp and base backdrops.
