Iron Frontier

Iron Frontier drops you on a snowbound edge of the map with a tiny outpost and a hard clock. You gather, build, and hold off waves that get meaner every night. What sets it apart is how much the map matters — a well-placed wall or a good road can save an entire run.

On a phone the pinch-to-zoom and drag panning are smooth, and I like that you can queue orders and let them play out while you plan the next move. The settings let you turn on a battery-saver mode that caps the frame rate, which I recommend for longer campaigns because this one can heat things up.

The difficulty curve is honest but steep. Losing a run stings, yet I kept restarting because I could always see the mistake I'd made. That's the mark of good strategy design.
