You bet they did:

Season 2 CNS/ “The Finals Hacked” theme:

• New gamemodes:

Powershift (tug-of-war meets convoy on a moving platform) Terminal Attack (Search & Destroy, but it’s hacking terminals instead)

• Sys$Horizon, new map, “unfinished/leaked” 80s style
• Hacking-themed gadgets such as the dematerializer and the gateway
• Weapons ofc (I don’t remember which ones tho)

Season 3: Japan theme:

• We don’t talk about ranked changes
• New game-mode: World Tour (similar to unranked tournament, but 8 teams total, win points progression and end-of-season multibuck rewards)
• Bow for light, dual blades for medium, winch claw for heavy
• Map: Kyoto 1568

Season 4: Sponsorships

• New careers: sponsorships
• Dual eagles for heavy, dmr for medium, shotgun for light
• Fortune Stadium: the best parts of previous maps, mashed into one and themed with the season sponsors’ colors

Season 5: Time for la fiesta, it’s the anniversary

• New map: Bernal, Mexico
• New gadgets: Black hole for lights, chain trap for heavy
• Shak-50 for heavy, some incendiary shotgun for medium
• Jukebox to relive all the OST from current and previous seasons
• 2 new sponsors, one returning

That’s only what I remember from the top of my head, they added so much. Not to mention the copious amount of high quality cosmetics and the very forgiving monetization
