You are a sniper whose mission is to free the hostages. You have to kill all the bad guys and do so before you run out of time to win! You have unlimited bullets but if you shoot any hostage, your mission will fail immediately.
This time, it snows!
If you cannot complete the mission, your score will be 0. If you have higher accuracy in shooting while completing the mission in a shorter time, you'll get a higher score. You will also have to complete your mission against wind influence under various weather.
Be the ultimate sniper and beat your opponent!
