28 new islands — 42 in all. Build a Ferrari Enzo, a T-90 tank in camouflage, a Su-47 jet with forward-swept wings, a hot air balloon, a steam locomotive with its own station, the Titanic and an ice fortress. Each island is bigger than the one before it: the last is close to 400,000 cubes. Day turns to night over the islands, and a comet crosses the dark sky. Photo mode hides the interface so you can capture your island. Every island you finish now records its size and your best time. Background music, off with the same button as the sound. Tap the island and the spot answers — a ripple spreads from your finger and the crew nearby speeds up. More crew speed and depot levels to upgrade. Fixed: the crew could stop working until you reopened the game. Free, with ads. Nothing to buy, no accounts, no sign-in.
