Cities Skylines 2 DLC list: Bridges & Ports (Oct 2025), Beach Properties, creator packs and Ultimate Edition — plus every CS1 expansion rated, with must-buys.
Cities Skylines 2 DLC Guide — Every Expansion & What's Worth It (2026)
The short version: CS2's paid content is still thin — 1 major expansion (Bridges & Ports, Oct 29, 2025) + 1 asset pack (Beach Properties) + a batch of creator packs and radio packs, plus the bundled Ultimate Edition. CS1, by contrast, has 11 major expansions plus 20+ content/radio packs, and the community-agreed must-buys are Industries, Mass Transit, and Parklife. Neither game needs DLC to be good — both base games are complete. If you're searching "cities skylines 2 dlc," you want "what exists + what's worth it," so here's the list and verdict for both generations.

The Complete CS2 DLC List (as of Aug 2026)
| Content | Type | Release | One-line verdict |
|---|---|---|---|
| Beach Properties | Asset pack | 2024-03-25 | Beach buildings/seaside housing assets; came with the 1.1 patch; thin on content |
| Bridges & Ports | Major expansion | 2025-10-29 | The only real expansion so far: bridges, docks, one-way roads, lighthouse landmarks, new zoning |
| Cold Wave Channel | Radio pack | 2025-10-29 | Radio music, pure vibes |
| Mediterranean Heritage | Creator pack | 2024 | Mediterranean-style building assets |
| Modern Architecture | Creator pack | 2024 | Modern-style building assets |
| Supply Chains & Skyscrapers | Creator pack ×2 | 2025-12-03 | Supply-chain buildings + skyscraper assets |
| Office Evolution | Creator pack | 2026-03-17 | Office building evolution styles |
| City Stations | Creator pack | 2026-03-18 | Bus/train/tram/metro station assets |
| Ultimate Edition | Bundle | — | Base game + Expansion Pass (Waterfronts) + content packs |
Tight budget? Buy only Bridges & Ports (the one that changes gameplay). Asset lovers: pick creator packs by style. Discounts are frequent (Steam 30% off is common), so don't pay full price. Content keeps coming via patches like 1.3.6f1 — the roadmap status is in the 1 vs 2 guide.
CS2 Bridges & Ports Deep Dive (Oct 29, 2025)
- Bridges: several new bridge types (including cable-stayed) solving the "city across the water" design problem.
- Harbors/waterfront: multi-lane docks, leisure piers, and a landmark lighthouse (doubles as a tourist draw).
- New: one-way roads (bike-related networks), new zones, and growable buildings.
- Bundle: shipped the same day as the Cold Wave Channel radio pack and patch 1.3.6f1; includes new maps (map gameplay in the maps guide).
- Reception: broadly positive — it's CS2's first "weighty" expansion and fills in the waterfront-city playstyle.
CS1 ran a three-year flood of 11 expansions; CS2 switched to a slower Expansion Pass (Waterfronts) + creator-pack model — less content, but each piece more polished. If you want CS1-style DLC oceans, only CS1 can give you that.
Every CS1 Expansion, Reviewed
| Expansion | Year | Content | Worth it? |
|---|---|---|---|
| Industries | 2018 | Full production chains (farming/ore/oil/forestry) | ✅ Must-buy |
| Mass Transit | 2017 | Ferries, monorail, blimps, cable cars | ✅ Must-buy |
| Parklife | 2018 | Parks and leisure districts | ✅ Must-buy |
| Green Cities | 2017 | Eco buildings and tools | ✅ Worth it |
| Snowfall | 2016 | Winter/weather (trams depend on it) | ⚠️ Fans only |
| Campus | 2019 | Universities/college system | ⚠️ Niche playstyle |
| After Dark | 2015 | Day/night cycle and leisure | ⚠️ Old but cheap |
| Natural Disasters | 2016 | Disaster system | ⚠️ Side mode |
| Sunset Harbor | 2020 | Fishing, transit hubs, etc. | ⚠️ Mixed bag |
| Airports | 2022 | Airport system | ⚠️ Only if you want the theme |
| Plazas & Promenades | 2022 | Pedestrian streets and plazas | ✅ Community favorite |
Industries → Mass Transit → Parklife change the game; buy them first. Green Cities and Plazas & Promenades next. Radio and content packs are decoration — skip unless you're a collector. Buying the full set on sale is the best value. How DLC and mods interact (e.g., TM:PE) is covered in the sandbox guide.
Do You Need DLC at All?
No. Both base games are fully playable:
- CS1's base game has a complete building loop (roads/zoning/power/water/services/traffic); DLC "deepens" rather than "unlocks."
- CS2's base simulation depth (economy/seasons/individual citizens) already beats CS1 plus most of its DLC.
- The standard Paradox advice: play the base game 20-50 hours first, find what you love, then buy DLC around it — buying backward is how you get buyer's remorse. And no DLC will save you if your PC can't run CS2 — see the system requirements guide for the real hardware bar.
