Is the CS2 map the official GTA 6 map?

No. It is a community recreation of an estimated layout. The real Leonida will differ in districts, scale feel, and countless details Rockstar has not shown.

What is map ID 153426?

The in-game Cities: Skylines II download ID for Noasden’s Leonida recreation. Search that ID after you own the game and required add-ons.

Do I need Map-6 if I have the CS2 map?

Yes if you want searchable POIs, collectible tracking, SEO guides, Shareable coordinates, overlay deep links, and filterable trailer scrubbing without launching Steam.

How should I study both together?

Pick a Map-6 regional hub, read the prose, open /map with Landmarks on, then walk the analogous district in CS2. Pause on a recognizable silhouette and Share a Map-6 deep link into your notes.

Can I use this for collectible routes?

Only as pattern recognition (rooftops, piers, yards). Log candidates against Map-6 landmarks and trailer timestamps; convert to Collectibles pins after launch when evidence is reproducible — see the hidden-packages guide.

Is Map-6 affiliated with the CS2 author?

No. We complement the recreation editorially. Always follow Steam’s page for the save’s own terms, updates, and credits.

GTA 6 Map in Cities: Skylines II — Explore Leonida in 3D

A fan rebuilt Vice City, the Keys, and Port Gellhorn in Cities: Skylines II (map ID 153426). How to load it, and how Map-6 complements the 3D walkthrough.

While waiting for Grand Theft Auto VI, a fan known as Noasden spent about 145 hours rebuilding the community-estimated Leonida map inside Cities: Skylines II — at a claimed 1:1 scale, with traffic and weather systems doing their city-sim thing. Steam map ID 153426 is the download handle. Map-6 stays your browser map for searchable POIs, collectible filters, HUD coordinates, Shareable deep links, streamer overlays, and regional guides. CS2 is the closest thing to a walkable 3D preview of the same community cartography lineage — including GTADB-style mapping credited under CC BY 4.0 where those assets apply upstream. Neither tool is Rockstar; both are useful when you refuse fake leak PDFs.

What was rebuilt?

The recreation covers Vice City, Vice Beach, the Leonida Keys, Port Gellhorn, and surrounding fabric. Expect beach neon that reads like Ocean Drive energy, causeway approaches that sell Keys travel time, crane clutter for Port Gellhorn industry, and transitions toward wetlands and wilderness that echo Grassrivers and Mount Kalaga on Map-6 regional hubs. It is based on trailers, screenshots, and community mapping — not official Rockstar files. Street names, interior layouts, and mission routing in CS2 are not canon. When the real game ships, treat CS2 as a nostalgia and teaching tool that will drift from accuracy. Use it now to train relative geography: where paradise marketing sits next to wage work, gated money, and humidity.

How to explore it in Cities: Skylines II

Own Cities: Skylines II on Steam (plus any required add-ons for the save). Missing DLC is the usual reason a map fails to load — fix packages before blaming the ID.
Open the in-game download / map browser and search for map ID 153426, then load Noasden’s Leonida recreation.
Lower graphics or pause simulation if you only need a camera tour; city-scale saves are heavy when you are sightseeing rather than governing.
Walk or drive a beach strip, a causeway, an industrial edge, then look for wetland and wilderness transitions — narrate them against Map-6 region names.
Flip to Map-6 in the browser: filter Landmarks, copy HUD X/Y, Share a deep link with optional theme and creator ref, and paste it into your notes or Discord.
Optional creator loop: keep Map-6 /overlay as an OBS or Kick browser source beside CS2 so viewers see verified pins while you walk fan streets — label both as estimates.

Map-6 vs Cities: Skylines II

Use Map-6 to search POIs, filter Landmarks / Collectibles / Secrets, copy coordinates, read /locations hubs (Vice City, Ocean Drive, Leonida Keys, Port Gellhorn, Grassrivers, Ambrosia Island, Mount Kalaga), and ship Share links that land friends on the same camera. Use CS2 when you want street canyons, bridge approaches, and a gut sense of travel time between neon and yards. Same community map ancestry; different jobs. Collectibles planning still belongs on Map-6 — CS2 will not magically place Rockstar hidden packages; it only helps you see rooftops and pier geometry that historically hide pickups. After launch, Map-6 absorbs verified pins; CS2 stays a fan snapshot. Editions (Standard vs Collector) are irrelevant to both tools — see the pre-order guide only if you are shopping for November 19, 2026.

This is a fan estimate inside a third-party city builder. It is not affiliated with Rockstar Games or Take-Two Interactive. Map-6 does not host CS2 assets — we link to Steam and help you cross-reference locations. We do not sell leak packs, invent interiors, or claim the CS2 layout is final Leonida geography. Credit GTADB CC BY 4.0 where Map-6 basemap lineage applies, and say “fan estimate” on stream when you show either tool.
