1. You're going to run into a wide variety of people playing in Olympus. There are a lot of cool people that play, but also a bunch of clowns that play. If you run into a clown, just remember that they don't represent the majority of players.
2. The Olympus Wiki has A LOT of information that can be beneficial for you. Server rules can be found there, along with rules for both Medic and Police factions. You won't be able to join those factions right away, but you can at least know what to expect when encountering each of them when playing as a civilian.
3. Have reliable recording software such as ShadowPlay GeForce. In the event that you are a victim of someone breaking server rules (ex. someone killing you without engagement), you can receive compensation for any lost gear/items with the proper video evidence.
4. Check the forums, or discord for any gangs that are recruiting and accepting new players. This game is a lot more enjoyable when you play with friends. Playing as a solo player is also viable, but be prepared to be outnumbered in just about every scenario you run into.
5. If you are in a helicopter and someone texts you, AUTOHOVER IN PLACE FOR 5 MINUTES OR BE TITANED, don't believe them and just keep flying. They are always bluffing.
If you have any questions or concerns, the Support Team is available. Either jump on teamspeak and wait in the Need Help channel, or use Discord to submit a ticket with your questions/concerns. Good luck!!
