" Under the Radar" success in GTA4?
Something I saw when attempting to get the success myself - - everytime you get among the bridges in the direction of the success it'll turn up a message claiming the amount of bridges are left, and also extra notably, the bridges you have not flown under will momentarily get a prize symbol on the map. If you most likely to the time out food selection, you can see all the bridges you have yet to fly under and also create a map pen at the next bridge you intend to most likely to. Keep in mind that the prize symbols just appear to last for around 10 secs after flying under each bridge, when out the time out food selection.
If you do not recognize where to get going, every one of the bridges that go across the numerous rivers around the islands are counted in the direction of the success.
This site clarifies why you're having problem.
This is the key exerpt :
Find the smokestack in Alderney's commercial park. If you have actually steered your helicopter below all 4 of the bridges that go across the inlet over Alderney's commercial park and also the video game offers you debt for just 3 of the 4 bridges, fly to the bridge situated at the opening of the inlet. Open the map and also locate the smokestack, which is shown as a grey circle. Action. 3. Maneuver the helicopter south of the smokestack. Fly your helicopter south of the smokestack, after that fly right in advance under this area of the bridge. Traveling under the area that goes across water will certainly not offer you debt. As soon as you have actually flown under all 14 bridges, you will certainly get the Under the Radar success and also receive 40 player factors.
