Star Trek Online launched on 2 February 2010 and has been free to play since 2011, which means the game a new captain meets in 2026 is sixteen years of accumulated systems rather than the one Cryptic shipped. The level cap has sat at 65 since the Victory is Life expansion, there are over 160 story episodes, and the newest expansion, Undiscovered, arrived on PC on 7 July 2026 and on consoles on 29 July. Almost every mission alternates between starship combat in space and a ground away team, so a build that only works in one half will stall.
Choosing the right build shapes your entire experience. This guide breaks down every option: what they're good at, what they struggle with, and which one matches your playstyle. For optimized builds with full gear sets, see our builds guide.
