Background

You play as Ryley Robinson, the Non-Essential Systems Maintenance Chief aboard the Aurora, a spacecraft sent to the Ariadne Arm by the Alterra Corporation in order to build a phasegate. Following the ships catastrophic hull failure and subsequent crash landing, he must find a way to escape from the water planet known Planet 4546B, and discover the cause for the Aurora's crash.

Beginning

Opening Sequence

After the Aurora's hull failure, Ryley enters Lifepod 5 and ejects the lifepod. It lands in the Safe Shallows, the first biome the player will enter. Following the cinematic sequence, the player will wake up, and after a short stuggle to get out of the chair, will stand up. This is when the player will gain control of Ryley. A fire has started in the lifepod, move towards the Fire Extinguisher on the ground, (see Key Bindings for game controls), and pick it up. Aim the fire extinguisher at the base of the fires and use it to put the fires out until you can no longer see their bright red and orange glow. After the fire has been put out you will boot up your PDA, a tablet that will act as a databank, inventory, beacon and screenshot manager, as well as act as your virtual assitant for the duration of the playthrough, giving game hints and anecdotes.

The Lifepod

Inside the lifepod there is a storage chest with a red top, inside the chest you will find two Nutrient Blocks and 2 Filtered Waters. These will serve as your food and water source until you are able to create your own. Along with these there will be 2 Flares, which can be used to light up dark areas until a more reliable light source is found. Also inside the lifepod is a Medical Kit Fabricator, which will automatically provide First Aid Kits for the player to use when they get injured. It is recomended to take a first aid kit so you have a way to heal in the event that you are attacked by fauna. Also inside the lifepod is the Fabricator, which is used to craft natural resources into other materials, kncluding food and wayer sources. Finally, you will see the Damaged Radio and damaged secondary systems. These can both eventually be repaired using the Repair Tool.
