Though definitely one of the oldest games on this list, Hellgate: London remains of the originators in the genre. “Shooters” weren’t really a thing before this game and Borderlands. However, this game predates the original Borderlands game and came from developers who had worked alongside Blizzard Entertainment.

While the single-player has a decent campaign, the multiplayer of this game is its bread and butter. Sadly, the 2018 Steam release of the game did not include the multiplayer facet. Fans of the genre looking to indulge in some of its histories should look into this title.
