GW2 The Long Way Around achievement guide with detailed description and video walkthrough. The Long Way Around is an explorer achievement introduced with the Halloween patch for an activity in Straits of Devastation. The activity itself is largely risk free as there are no mobs around but there is a timer on it and it can be quite annoying/frustrating (achievement originally discovered by Taeril)
To start off, head to Fort Trinity in Straits of Devastation and swim to the open left of it. You will want to search around the location indicated on the map for a cave entrance.
Note: Apparently on some worlds you don’t have to mess with the datapads and can swim through a gap on the top left of the force field to get the achievement.
Once inside, you need to find the location of the six Asuran Data Pads and be familiar with their locations. You cannot interact with them if you have the Corruption buff on you from the Risen Hands and fish corpses around the water. You need to disable all six data pads within a time limit of ~ 10 minutes before reset. This goes a lot easier and faster with a friend or two.
Here is a video to help you familiarize with the location of the six data pads. (Tip: hold down left ctrl to easily find the data pads).
1 & 2
Look to your left from the entrance, Data Pad 1 is on the wall to your left and Data Pad 2 is just above it
Look to below you and to the right after 1& 2, there is data pad 3
Past #3, you will see a bunch of fish corpses on the left wall, data pad #4 is right there!
#5 is at the back and probably the hardest one to reach without getting the Corruption buff. You will want to start off with this one first so that the timer starts with this datapad as the others are a bit easier to reach.
#6 is to the left of $5, near the dome/barrier for the final part of the puzzle.
After activating all 6, the barrier at the end opens up and you can swim inside for your achievement.
You will need to 1) avoid the stuff that Risen Hands through at you, 2) Don’t run into any Fish corpses 3) Deactivate all 6 pads within 10 minutes of the deactivation of the first pad. If you get the corruption buff on you, you will be unable to deactivate any pads and need to swim back to entrance to talk to the NPC to clean it off.
Make sure you get Pad #5 first as it is the hardest to reach and can take a while before you successfully deactivate it.
