- You're a scout charting habitable worlds. Some sectors of every map hide hostile aliens.
- A number is a signal: how many hostiles are in the 8 sectors around it.
- You can't just tap to explore. Play a card: tap it, tap the map to aim, tap again to fire. Its shape is where you jump.
- Any hostile inside the shape attacks and you lose hull. Flagged sectors are skipped by shapes.
- With no card picked, tap a dark sector to flag it.
- Cards cost fuel. Out of fuel, you pay in hull. Worlds and caches refuel you.
- Chart the worlds the sector asks for, then Warp. Chart them all for a ship module.
- At the starport, draft a card and spend credits. Reach the eighth sector and find the Cradle.
