Subnautica is a PC survival game set entirely underwater, where you explore alien oceans, build bases, and avoid terrifying sea creatures (like the Reaper Leviathan). For PC players who’ve completed the game, what’s the most terrifying or awe-inspiring creature you encountered, and how did you overcome the fear of exploring deep, dark biomes (like the Lost River or Lava Lakes) to progress? Additionally, base building in Subnautica is focused on underwater functionality (e.g., oxygen production, food storage, vehicle docks)—what’s the most essential part of your base design, and how did you adapt it to different biomes (e.g., building a thermal plant near lava vents for power)? Finally, the PC version has mods that add new biomes, creatures, or quality-of-life features (like a better map)—have you used any mods that extended your playtime, and did they keep the game’s focus on exploration and survival intact?
