Option 1: Introduction, no min/max strategies. Good for beginners.

• make 2 blue tablets, 1 purple tablet, 1 hatching enzyme;
• leave lifepod and release MVB, create Seamoth;
• pick up MVB, enter Seamoth, and drive to the bulb zone Lost River entrance; [Holding A+Space as well as W helps you go much faster than normal (tri-planing)] [Holding 'down' (usually ctrl or C) instead of Space makes descending faster while triplaning]
• descend through Lost River, Lava Zone, across Lava Lakes, to PCF;
• open Blue doors and enter Aquarium, and wait for the invisible wall to drop ("they played alone...");
• collect the top-back ion cube, then bottom cave ion cube;
• activate hatching platform and use the enzyme;
• wait for Momma to blow the sand from the portal and activate it, go through, then use a cure ball;
• swim straight up to the surface and release the MVB facing towards the QEP, and build Neptune platform;
• swim down to QEP moonpool entrance and run up the ramp-room to the control room to disarm the gun;
• jump down the ramp room and swim back out the moonpool, and up to the Platform.
• build the rest of the rocket, leaving the console when the cockpit begins building.

Option 2: Advanced, including min/max inventory and movement strategies

• make 1 blue tablet, open inventory, assign MVB to '5', then make 2nd blue tablet and leave lifepod;
• Release MVB, pick up MVB and re-release facing approx. towards the Aurora. Create seamoth;
• push MVB towards seamoth, pick up MVB, enter Seamoth, and drive to the bulb zone Lost River entrance; [Holding A+Space as well as W helps you go much faster than normal (tri-planing)] [Holding 'down' (usually ctrl or C) instead of Space makes descending faster while triplaning]
• descend through Lost River, Lava Zone, across Lava Lakes, to PCF;
• open Blue doors and enter Aquarium, and wait for the invisible wall to drop ("they played alone..."); (at this point make sure propulsion cannon is bound to a quickslot like 1 or 2)
• collect the top-back ion cube, then bottom cave ion cube;
• activate hatching platform, swim towards Momma's tails until she turns quickly (momma skip);
• build moonpool and a fabricator on the rim of the moonpool, craft hatching enzymes and drop ion cube;
• start purple tablet crafting, pick up ion cube again, insert hatching enzymes;
• collect purple tablet, seaglide to the exit portal and wait for the pedestal to open so you can activate;
• go through, switch to propulsion cannon and capture a cure ball, and launch it vertically;
• swim straight up, collect the cure ball with prop cannon again when close, and launch again to the surface;
• just beneath the surface, release the MVB facing towards the QEP, and build Neptune platform;
• use the cure ball at the surface, then dolphin dive onto the Neptune platform and build the gantry;
• swim down to QEP moonpool entrance and run up the ramp-room to the control room to disarm the gun;
• jump down the ramp room and swim back out the moonpool, and up to the Platform;
• build the rest of the rocket, leaving the console when the cockpit begins building.
