GTA 3 Gameplay Walkthrough - Mission 23: Under Surveillance (Asuka)
For this mission, you are given 6 min and 30 sec to drop 9 Mafia men. If you don't have the Sniper Rifle, get one from AmmuNation Gun Shop (follow radar). Grab some grenades while you're there.
In Belleville Park and take a position far enough from the small island in the pond that the 2 Mafia men can't see you or get a true shot at you. Use the sniper rifle and aim for the melons. Drive to Bedford Point and toss a grenade at the Mafia's van (located on radar). When you take this van out many police will begin pursuit, so quickly reenter your vehicle and head to Torrington.
Use the stairs to climb to the helicopter pad on the top of Kenji's Casino. There are 7 Mafia men on the opposite building. Use the Sniper Rifle to pop the Mafia men on the different balconies on different floors. Start with the top and work your way down. Expect return fire but don't let that rush your aim, they carry Uzi's and at this distance they are not too accurate. When the last one is down and there is time left on the clock you will pass the mission.
