  • View the photos they have taken. PDA Photo Manager Icon.png
  • View their log messages PDA Log Icon.png
  • View their Databank PDA Encyclopedia Icon.png
  • View all received Time Capsules PDA TimeCapsule Icon.png

The PDA's AI keeps the player informed of their health status and will alert the player when the player has 30 or 10 O2 points remaining, or if the player is getting close to dehydration or malnutrition. It also gives useful information to the player when they enter new areas or find new materials.

Abandoned PDAs can be found inside and around Degasi Seabases, the Aurora, Destroyed Lifepods, and some Wrecks. These can be collected to download their log messages.

Data Bank Entries

If you are reading this, then you have survived an emergency evacuation of a capital-class ship equipped with Alterra technology. Congratulations: the hard part is over.

Your PDA has automatically rebooted in Emergency Mode. This operating system has one directive: to keep you alive on a hostile alien world. If that is not possible it will alert salvage teams to the location of your remains.

It features:
- Full monitoring of vital signs for timely survival advice
- Blueprints for fabricating a range of essential survival equipment, tailored to your environment
- Onboard camera, microphone and OCR technology for short-range situational analysis - Cross-compatibility with all Alterra-compliant products

NB Your personal and work files have been encrypted and may be retrieved at a later date by a licensed engineer.

1. Administer first aid if required
2. Take inventory of available materials and supplies, and decide on rations
3. Survey the environment for threats and resources
4. Construct necessary survival equipment using the lifepod's fabricator
5. Check lifepod for damage, and repair as necessary
6. Broadcast local distress signal using lifepod's short-range radio
7. Locate other survivors using line of sight or the radio
8. Find or construct a more permanent habitat
9. Maintain physical and psychological health until rescue

NB This information is meant as a general guide. In the first instance you should always follow the advice of your PDA, which has taken your particular circumstances into account.

Damage to your PDA's hard drive has corrupted approximately 80% of stored survival blueprints. Blueprints may be reacquired by scanning a salvaged technology using the handheld scanner, or by downloading plans from a ship-board databox. In the circumstances these assets will most likely be found amongst wreckage from the Aurora.
