Season One: Common Ground
Season One: Common Ground was released on March 24th 2010.
 PvP Updates
Two new PvP updates are scheduled to be released as part of Season One: Common Ground: a Federation vs. Federation PvP battleground, presumably for space combat; and “Shanty Town”, a new PvP ground assault map for both Klingon and Federation players.
New customization options include off-duty outfits, new hairstyles, two new stances (Stern and Relaxed), and “The Captain's Log”, a web-based application that will allow you to check in on your own or your friends' Captains and starships outside of the game.
Three new Fleet Actions will be introduced: “The Big Dig”, which takes place in Romulan space; a full-scale invasion by True Way forces of Deep Space 9 in “DS9 under Siege!”; and the ability for Klingon Captains to access the “Crystalline Catastrophe”, Big Dig and “Breaking the Planet” Fleet Actions.
The long-awaited respec system will be implemented in three different ways: as a C-Store purchase, as an in-game reward for ranking up; and as a purchase in exchange for Starfleet Merits from Skill Trainers. Furthermore, three new skills will be introduced: Starship Attack Vectors, Combat Maneuvers, and Starship Battle Strategy.
 Cryptic Store
Besides the respec system, players will also be able to purchase new Bridge variants, new Federation Starship variants, additional character slots, official name changes, and three new playable species: Tellarites, Pakleds, and Rigelians.
 Lifetime Subscriber Perks
Lifers are now recognized both on the official STO forum and in-game by a special Career Officer title. Lifers also have access to the Captain's Table, an exclusive area in the area right outside of Earth Spacedock, as well as a special uniform combadge (the Starfleet delta logo over a sizable starburst emblem).
 Test Weekend
Season One was first released on Tribble 10 March 2010. Cryptic held a Tribble Test Weekend from 19 to 23 March 2010 prior to the release of Season One. Players who participated received the Tribble of Borg and Crash Test Tribble player title as rewards.
