Create a CTF (Capture the Flag) match and have one player capture the flag three times to win the round. To save time, I’d enable fly with objective so you can just hop in a warhawk to capture faster.

I could only get this to work online with a friend in a private match. It didn't work in pre-game or splitscreen.

Create a zones game and ensure it's 10 minutes long with a 5000 point win score so you have enough time to capture all the zones. Just hit “select” to view the different zones; capture each one to level three. I had my friend level up his base to level two and I reduced it back to one.

The trophy unlocks at the end of the round.

Have the other player hover a warhawk close by. Just use the pistol and grenade to blow it up. Using more powerful weapons such as an AK damages the Warhawk faster; don't use a rocket launcher.

Grab a sniper rifle and double zoom using L3. Have the other player go far enough back that he appears as just a small dot/outline. Kill said player and the trophy should unlock. If it doesn’t unlock have the other player move further back.

Few ways to do this, the easiest is to pick up the Bio Field Generator, which you can throw to create a health regeneration field. While standing in the field have the other player shoot 3 magazines of AK rounds into you and it should unlock.

Enable same team split screen if you are doing this alone. Just get in a 4x4 and have the other player jump in the gunner spot. Drive to the flag, wait while the other player picks up the flag and gets back in. Drive them back and let them capture it and it should unlock.

Both people get in a warhawk; have your friend (player 2) hover in his. Fly around grabbing the green swarm missile pickups. Once you have 8 missiles line up far back to where the red targeting reticule turns white, then move just with-in range so it turns red again. Hold L1 until the lock-on stops. Once it stops, let go of L1 to release all 8 missiles on the enemy and it should unlock.

To get this achievement, just tap L1 to fire a missile at the other pilot. This one is done easier if you are closer to the other plane. I used the homing missile as it does more damage.

Pick up a TOW Missile power-up and use it to destroy the other players hovering warhawk. If you miss the plane, turn the missle around and try hitting it again.

Pick up a Cluster Bomb and have the other player sit in a warhawk just hovering above the ground. Hover over the other warhawk and drop it to kill him. It may take more than one Cluster Bomb but it can be done with one.

This one is easier with a human as the other player, as opposed to doing it yourself. Pick up the purple Aerial Mine power-up. Line up both warhawks, hovering in the air. Hit triangle to enter flight mode on both birds and then have the plane in front deploy a mine while flying into it using the second plane.

Alternately you can have one warhawk hover and fly towards it as you pass it hit L1 to drop the mine and if it's close enough it will kill the other warhawk and unlock the trophy. - Thanks to b_bellissimo69

Similar to Overkill but the plane getting shot at must deploy the white Chaff power-up to prevent himself from getting hit. Make sure the red bar at the top has at least 6 red squares under it so you are in fact losing at least 6 missiles.

This is the easiest gold medal thus far. Just create a server but change the “player” option to “dedicated”. Once you start the server, a total clock in the bottom of the screen will count up. The trophy unlocks when that timer reaches 4 hours. Just leave your PlayStation 3 on and go watch TV or a movie or something.

Ensure you create a RANKED SERVER, otherwise you will not receive the trophy!
