Sonic Frontiers' final free update, The Final Horizon, launches later today, and ahead of its release, SEGA has dropped a brand new trailer which shows off gameplay from all four playable characters.

The Final Horizon will be available to download from 5pm PST / 8pm EST / 10pm BST today, 28th September, and will allow you to play not only as Sonic, but Tails, Knuckles, and Amy, and we get a brief look at all of them in action. Long-time Sonic fans will be delighted to see the Cyclone, Tails' mech from Sonic Adventure 2, while Amy and Knuckles' gameplay focuses on combat and platforming.

Three new playable characters are good enough for free DLC, but this new update will also deliver some brand new story beats, challenges, and more, all in aid of a "climactic" end to Frontiers.

Here's a rundown of the DLC's plot from SEGA:

The additional narrative takes place before the final battle on Ouranos Island, where Sage reconsiders an unlikely scenario amongst her millions of calculations. With the assistance of Sage and Dr. Eggman, Sonic sets this new plan into motion, and accepts the challenge of converting the Cyber Corruption into a vast, previously untapped power source. Meanwhile, Amy, Knuckles, and Tails seek to do their part and begin searching for the Chaos Emeralds on Sonic’s behalf to change their fate.
