    You can rush this on Easy as The Arbiter. Build one Power Extracter, then just build Harvesters. Split up the Grunts you started with, and go round the map building Unstable Barrels (they cost 100 Supply). If any do get destroyed you will need to rebuild them. Build a couple of Minibases as you go, and more Harvests to speed up the rate you generate Supply. Build a couple of Turrets near the Terminus, as that should be enough to handle the enemy on Easy for at least the first 10 waves. As soon as every plot has a wall on it at the same time, the achievement will unlock.

    The best way to do this is playing a co-op game of 2 players on easy difficulty. Do not change any additional options in the menu or it won’t work. If you play with 2 other players, this means a 3-player team, the map will be bigger, and you will have to build more walls, also the enemy waves will be bigger.

    I think the best way to do this is having one player focusing on creating units (I recommend air units, but other units also work well) and expanding in the map, while the other focus on collecting supplies to build walls (he/she can also help with some units, but don’t create a big army).

    When the game begins, stay and protect the starting area (Terminus and main bases). Build walls and turrets and start building a good economy. After wave 6-7 when you and your friend have supplies and an army, go and dominate one of the unexplored sides of the map, building the bases, walls and turrets. Don’t stop training units to defend your bases against enemy waves!

    Once you have that zone controlled you can make your way to the other side of the map. Now just use all your supplies to create walls. Once you built a wall in every slot the achievement will pop.

    Edit: I can confirm that any type of wall counts for the achievement, as long it's construction is finished.

    NOTE: It seems like any type of wall counts for the achievement. When I did it, I used different type of walls, including Banished-UNSC walls, and the achievement popped.

    Play firefight on easy mode, choose Pavium. Try to get the Burnout power as soon as you can, and upgrade it every chance you get. Once you get it, use burnout on your resource and generator buildings. Then once you are comfortable start building walls, or barrels as they are cheaper, try to build them in areas that the enemy isn't walking through first, and then slowly wall them in. Also, use the mini bases to build mega turrets, which will help kill ground and vehicle troops. With this method, you can also complete Pristine, and Survivor in the same match.

    When I used this method I had a seemingly unlimited amount of resources around round 20 or 25, and I didn't have any issues building the rest of the walls. I also used banshees and engineers as my main troops, as I could easily navigate the map with them.
