Countdown was one of the Galactic Ranger missions of Operation: URBAN STORM on Kerwan. The Tyhrranoids occupied Metropolis and planted timed explosives throughout the city. The mission involved destroying all the 6 timed bombs with the Hovership in less than 2 minutes. The reward for completing this mission was 10,000 bolts (40,000 in Challenge Mode).
The red dots on the minimap signify enemies, the green are the explosives. To complete this mission without much trouble, simply focus on finding and shooting at the bombs, which are located on some of the city islands and towers, ignoring the Thyrranoid forces around.
