Star Trek Online's 14th anniversary event featured the addition of a new multiplayer activity to the roll: The Battle of Wolf 359, where a team of players essentially cosplays through a simulation of the bloodiest single battle in Starfleet history prior to the Dominion War.
At Wolf 359, a group of 40 Federation starships got thoroughly wiped by the OG Absolute Unit, a single Borg Cube. In STO, this takes the form of a multi-phase giant boss battle where your team shuffles between fighting hardpoints on the cube's surface, rescuing escape pods from destroyed ships, and taking out assimilation probes that launch out of the cube.
To promote the addition, Cryptic worked with fan artist Pundus to create a size chart for the ships included in STO's take on the battle. It's not 100% canon, and takes advantage of Trek lore's holey nature to include a few shout-outs and STO originals. It's also apparently based on the fan novel "We Have Engaged the Borg."
For example: Since the Akira-class and Lower Decks' Parliament-class have no specified launch date, they could easily have been around at that point in the TNG timeline. Similarly, a variant of the definitely-from-the-same-era Ambassador-class, the Narendra-class, shows up in "prototype" form. Same deal with a few "unidentified" ships from the batle that were replaced with STO originals like the Shikahr-class (a Miranda-type ship with TNG aesthetics), the Georgiou-class (a variant of the Walker and Centaur with the same style as the Excelsior)
Cryptic also took the liberty of jazzing up the in-game representation of Wolf 359 itself. Until this year going to Wolf 359 brought you to a kind of cheapy looking holo-memorial thing with a big projection of the starfleet logo and a bunch of nondescript ship debris.
With the patch and the addition of the actual battle to the sim rolls, Cryptic revamped the whole area, taking a cue from Picard Season 3's ship museum concept to create the Wolf 359 Memorial station. All of the ships from the above post that weren't completely vaporized by the Borg cube in the battle had their battle-damaged hulls recovered and put in a museum-style berth along the station's dock.
It's a fun little tribute only marred by the fact that Wolf 359 is a dim red star which means the entire area has absolute dogshit lighting
