Before obtaining any other flags, obtain the special flag depicted by the blinking yellow dot on the blue overview map on the right.
The achievement will not pop until the game is finished. It is earned when the first flag obtained in a round is the special flag depicted by a red S
in the field of play and by a blinking yellow dot in the blue overview map on the right.
The special flag is randomly generated and is in a different position each time. In the above video, it is on the far right fairly close to the bottom. Since the achievement is not unlocked until 'Game Over', in the video, to hasten the game's end, the player car suicides. Following the game over screen, this achievement along with four others are unlocked.Note
: The special flag doubles the value of other flags obtained in the round. Accordingly, there is a benefit to obtaining the flag early--preferably before other flags. If the player dies before the round is complete, the bonus will not apply to further play in the round.
