Edit: 14th September 2019 - an update has been released to fix the problem with the achievement not unlocking when it should. Thanks to snickerdoodle
for letting us know.
This achievement is Buggy -. Some people have managed to get it to unlock by getting all 3 wins in the same session. Vash 1he Stmpde
recommends that if this doesn't unlock for you that you complete one match on each map from the Warzone Firefight
posted this useful information in the comments:
From the main menu select Multiplayer
from the Playlist and press
You need to win a match that you have been in since the very start on each of these three original maps:
- Escape from A.R.C.
- March on Stormbreak
- Raid on Apex 7Warzone
is for 18 - 24 players, with a Fireteam limit of 12. The winner is the first team to 1000 points, or to destroy the enemies Power Core. Each game can last half an hour, so this is going to take a while. If playing by yourself you will just have to hope you are on a good team and that you get the map you need.
There are 3 bases (East Armory, West Armory and a central base whose name changes on each map) to capture and control, and you will earn points for each one that is held. Only when you control all 3 bases can you attack the Power Core at the enemies home base. You gain points for killing members of the enemy team and for killing AI enemies. However the biggest rewards (150 points) are for your team landing the killing blow on a Legendary Boss (indicated by a yellow marker), so this is your top priority. You can snatch a game back from the brink of defeat by killing one of these bosses, or lose a match just as quickly.
You will get another achievement at the same time, or beforehand:
