Four new things I want to say:
1) In the movement section, under 'Stalker mode,' I see a typo. Melee is misspelled.
2) About conning off-screen: enemies are the star-shaped symbol, and crewmates are the rounded symbol. Non-crewed players are not marked. The size of the symbol grows when the character gets closer to your screen. The symbol gets brighter as you approach the next screen.
3) On the PDA, a dark blue dot indicates a friend on your layer (instance). A light blue dot with a tiny arrow on it indicates a friend on another layer. Click it to switch layers. Crews will always be on the same layer. Joining a crew on another layer will move you to them.
4) Common bug: I can't sell my ring! Why can other people sell theirs?! (The more places the guide answers the soulbinding question, the more likely a newcomer is to see the answer)
