This guide will be going over all the achievements in Soma. A majority of these achievements are unmissable story achievements. There is only one miss-able achievement at the very end of the game, but other than that you should be good.
This guide has a video version over on YouTube, if you like this guide or the video check out the other guides on my channel.
There aren't any achievements until this section of the game; this achievement is earned when you talk to Catherine Chun at this phone station.
It takes a while to get to this next one. After you are able to leave out the hatch and get in the shuttle on your way to Lambda, you crash. You get "Chasing Catherine" after the water drains.
When you get to the next shuttle after a brief cut scene, the shuttle will crash at Peak Delta. After you crash you get "Stranded".
After you get to Peak Delta, you need to head over to the com center and make the blue part cover the yellow line, enter the number five, and it gives you the code 049. Then you can go over to the landing platform to request a zeppelin with the code 049. After that you need to shoot down a robot to get it ready to leave. Then you take the zeppelin over to Theta. Once you go in the doors and drain the water you get "The DUNBAT".
After you get everything you need and start up the Brandon Wan simulation with Alice, the DUNBAT falls, breaks, and you get the achievement "Plan B".
After you escape through the maintenance tunnels and go through the mesh opening onto the ocean floor, you get "Killed the Dream I Dreamed" for escaping Theta.
After you run around Omnicron and get the new parts for your body and upgrade it, you get "A New You".
This achievement is the only miss-able one. After you make your way through Tao and get to the woman guarding the Ark, you can get "Endangered Species" for talking to the last person alive. Talk to her for a minute before continuing the game.
After you put the Ark in the space shuttle, you get "Your Expressway to the Stars".
During the after credits scene, you get "The End".
