Far Cry 3 Blood Dragon

There are five braincaged dragons in the mission, "What Is This Shit?". They're all in the dragon egg area.

Burn the first group of eggs (just a single group, NOT an entire 'patch' of eggs - you do NOT want the objective to say 1/3). Two or three dragons (normally two) will appear. When you have removed the braincages of these two dragons, and THEN killed them, burn another single group of eggs (again, not an entire 'patch' of eggs). A third dragon should appear. Destroy his braincage, and then kill him.

You should always use your Terror 9000 weapon for killing these dragons. If at any time do you run out of ammo, run back to the vending machine that was next to the control that opened the door (where the snipers were waiting for you). You can get a free refill of ammo (to 700 bullets) if your Terror 9000 is empty by switching it with the bow in your inventory, and then switching the Terror 9000 back out.

Now destroy the first patch of eggs that you already burnt some eggs in. Now move to the next patch. When you burn some of these eggs, a 4th dragon should appear (it's possible that you'll get the achievement early, on this dragon, if you don't, continue.). Destroy his braincage, and then kill him. Now destroy the rest of the eggs in all the egg patches.

When you've done this, you'll be told to evacuate. Get back to the elevator. When you activate it, a 5th dragon with another braincage will come after you. Destroy it's braincage, and then kill him for the achievement, if it's not popped already.

This is a guide for those who missed their chance on the story mission.
There is a way to find more braincage dragons. You need to use the reset garrisons option (pause-options-gameplay-reset garrisons) to get them, so make sure you've done everything you need to using garrisons (capture them all, use as teleport points for collectible finding, etc).
Once you've done this there are a couple of garrisons you can use, I suggest the one that is north-east of the dam at the far west of the map. (coordinates 476.7, 470.3). There is a dragon with a brain cage right outside this. Shoot this off and kill the dragon if you want. Then you can reset the garrisons and the dragon will be back, with it's braincage on.
Repeat 5 times for the achievement.
Resetting garrisons is also a good way to get money for upgrades, as you can go round and capture them all again.

EDIT: Curtieson adds that you don't even need to reset garrisons to do this. Go to the garrison at (476.7, 470.3) and shoot the braincage off the dragon. Then fast travel to another garrison nearby, and drive back to (476.7, 470.3). The dragon should be back, with braincage on. Repeat 5 times for the achievement.

This achievement is missable as there are very few braincaged dragons in theventire game.

Some dragons are mind controlled by a little red box on their forefront. Simply shoot it until it explodes and before killing the dragon. Repeat this 5 times to get the achievement. Note that if you reload a checkpoint to a previous state after destroying a braincage, it won't count anymore.

You'll find those dragons in some missions (especially What is this Shit? where you burn eggs and the last mission) and sometimes near certain garrisons (I got one in 2 different garrisons).

Thanks guys for the additional info in the comments.

I didnt make this video, but it does show exactly what is needed to make this achievement pop! Hope this helps and happy gaming guys! :D

This achievement is no longer difficult to get. If the achievement has not popped once the final level is beaten you are not stuck to wander and hope.

Once you complete the game to your content you can press Start -> Gameplay -> Reset Garrisons. This will make the Garrisons Red and repopulate the bases with Omega soldiers.



There is an underground base to the left of where you start out that has a Brain Cage Blood Dragon at the opening. The garrison that is directly south of where you start out also has a brain cage blood dragon to which you can easily pop off. Rinse and repeat until the achievement pops.
