Cryptic recently announced a new event for STO, starting next month. It's basically a recruitment event for new (and returning) players. They call it Delta Recruitment. The idea behind it is that the 'allies' need recruits for the upcoming Iconian war. It's more than just a simple event to get new players into the game though.
New characters made during the event get some bonuses:
- Access to some new story missions
- A nifty delta character next to their name
- Dilithium for enemies killed. This is just for the duration fo the event though. They also give people in their group dilithium.
- If you finish a faction story, you get an account wide starship trait
- Other special rewards while leveling
- Contributes to server wide goals that provide bonuses for everyone
- Free character slot
