Chronomes are unique combinations of characters, ships and time capsule configurations in Sine Mora. Chronomes can only be accessed in Arcade and Score Attack. Playing at least 25 different chronomes is required as part of obtaining the Inter Caecos Regnat Strabo achievement; the Suaviter In Modo requires playing at least 40 chronomes, while Fortiter Fideliter Feliciter requires playing through every single chronome.
