Grand Theft Auto IV Achievements

Under The Radar

40
Fly underneath the main bridges in the game that cross water with a helicopter.

Obtain a helicopter by going to the helitours area, or any other means you feel most comfortable with and fly under each of the following bridges:

There are 14 Bridges that are needed for this achievement. When you pass under a required bridge, a message will pop onto your screen letting you know you successfully went under, and how many you have left. If you go under a bridge and do not see the message, go back under it again, because it didn't count.

 Helicopter Control Tips:

-Ascend using the until at a reasonable height above the water and a few hundred metres from the bridge.
-Hold forward on the to start the helicopter moving forward, then release the
-Descend using the , you will still be travelling forwards
-Once under the bridge, you should have enough forward momentum to take you under, use to descend and to ascend as you move under the bridge to avoid hitting the water or the underside of the bridge.

Low Bridge tips:

This bridge only took me one attempt, but was hard nevertheless. The trick is to hover the helicopter's "feet" in the water as you move very slowly forward. Because this bridge is so low and there is not much of a run-up, you will need to control your speed using the BEFORE attempting to go under.

**Note** You do not need to do all in one flight, but it can be helpful to make sure you don't forget which you've done and which need to be done.

Here is a video of it being done: http://ve3tro.com/gta/under-the-radar.mp4

**Can be done after completing story mode**

My suggestion would be unlock all the cities first as 4 of the required bridges are on the last island and will therefore get u 6 stars buy flying near them.

It shows you the what bridges you need to fly under with a Trophy on it, when you check the map flying a Heli. Just make a waypoint for each bridge with a Trophy.

I swear to god I've gone under all of them with no success.. does spawning a helicopter really block the achievement?

Correction. spawning one of those attack helicopters will NOT block this achievement. but I suggest to use the yellow tour helicopters for they're smaller and a lil easier to work with.

smooth. i bet its the final one at very left. its by a nuclear pipe. you have to fly under the left part of it. not the part directly over the water. this took a while for me to figure out.

Actually liked this one. :) It takes a minute to get used to the controls, but this achievement's pretty easy once you do. Even the low bridges aren't too bad.

I just finished this cheive today. I enjoyed it, wasnt too difficult. If you are having troubles flying the helicopter , try to push the left stick up in a rhythym to move forward. also dont want to much acceloration for this, so do the same with the right trigger. use them together. just follow the beat to a song on the radio :P

This achievement made me hate flying helicopters in this game.

The Dukes Bay Bridge is a tough bridge to go under. When you go under a bridge, the game records it so you could save and continue another day.

aaaaaaaaaaaand I'm stuck at 13 bridges flying around the island. Anyone who's doing this achievement should record every bridge they go under. You'll need the 3 islands also.

I agree with @15. Now, this is very simple, go under random bridges until you get to 10 bridges left. Then, the bridges that are left will show on the map as trophies. Now before the trophies disappear, put a way point to one bridge. Keep doing this until you have finished all the bridges. I did this achievement in GTA The Ballad of Gay Tony, so all the islands were already unlocked. Also, I did this in the Annihilator (the big helicopter with miniguns). I would recommend doing this in the small 'Maverick' helicopter. Finally, I only had trouble with 1 bridge which was the low bridge to the West of the map.

The best technique to use when trying this achievement is to approach very slowly, as close to the bottom of the bridge when flying under. Also, if you hit the underside of the brid
