EDF3 Portable trophy guide

Kill related trophies:

Ant Killer:
Level 58. You'll most likely get this naturally while playing

Spider Killer:
Level 16 or 54, while grinding for armor or weapons inside nest.

Gunship Killer:
Level 34. Most time consuming kill trophy
-Take Pale Wing and use Mirage15WR
-Kill off all your allies and damage the fortress to the point where the laser cannons activate
-Kill off cannons and all waves of ants and robots
-Fly on top of the highest building you see preferably far away from the fortress
-Aim upwards so 15WR cannot damage the fortress and leave the fire button pressed
-Gunships will slightly damage you so will take little damage over time, a few thousand should be enough to last over a night
-In one minute you should get somewhere between 10 and 16 gunship kills

Carrier Killer:
Level 39. Simply shoot off all carriers and restart.

Hector Killer:
Level 57

Fortress Killer:
Level 34. Ride the bike and quickly snipe down the fortress.

Queen Killer:
Level 56.

King Killer:
Level 43.

Attacker Killer:
Level 51. Possible to farm by leaving fire button pressed with homing weapons.

Red Killer
Level 53.

Mothership Killer:
Level 60. Don't have to wait for MISSION CLEAR message, simply restart after you destroy the core. There is also no need to do anything in the level besides waiting for the cannon to appear.

Tank Master:
Levels 12, 37, 50 and 58. You should work on vehicle related trophies whenever you can.
-In level 58 you can use maximum paralyzer to stun enemies falling from carrier and then shoot them with your tank

Helicopter Master
Level 42. Kill off everything besides the carrier dropping red ants. Position the helicopter so it shoots the spot the red ants land on. Leaving fire button pressed you'll get all the kills needed in about an hour

Bike Master
Level 37 or 23. Impossible just leave the fire button on. In 23 kill everything except the red ants nest and farm the ants. Alternatively faster method is level 37 without destroying any nests and restart when your bike breaks up. Be sure to use Limit Booster

Vegalta Master:
Level 58. Simply farm the left carrier and shoot off the ants when they fall.

Tips and tricks:
-To remove the weapon and armor limit in multiplayer you must clear 70% of missions on either Storm or Pale Wing
-Pale Wing unlocks when you clear Level60 (You can simply go online and ask the host to select the mission)

Weapon farming:
This doc is slightly wrong since it's based on EDF4 instead of EDF3 but it's been confirmed you can get up to lv92 weapons in level52 inferno. For Storm there is a level93 and 94 weapon so you will have to farm higher levels for those.

Level 56:
Weapons needed: C70 and a sniper
1) Fly Helicopter over the tank so the tank is covered in the helicopter
2) Enter and leave the tank (If you don't get the position quite right you can try moving the tank while it's clipping within the helicopter)
3) You will be teleported outside the map in a completely black space. Leave a C70 here
4) Get on the helicopter and fly upwards until you reach the ceiling
5) Get off the helicopter and stand on the right wing. Explode the C70, all eggs will now hatch and all 3 Queens will now aggro you (If a Queen gets stuck on a building you can shoot them with a sniper to get them below you.
6) While maintaining your altitude keep throwing C70s down. Be sure to wait long enough for the C70s to make it all the way down.
7) Drop down once only few enemies remain and collect all items
NOTE: This is only doable in single player since the glitch does not work in multiplayer

Getting on and off helicopter while flying:
-When you press select you will get out of the heli just slightly in front of the right wing and you will drop down¨
-You will have to press your left analog stick lower left while pressing select to get off the helicopter
-It is better to start moving before pressing select to avoid falling
-Before doing this in mid-air, it's recommended to practice on ground

Pale Wing:

Level 28:
Once you have decent a thunder bow

Level 41
