Open the correct Roblox experience
Use the official destination and confirm place ID 125496078313264 with creator Blackbox Tycoons. This prevents instructions for a similarly titled experience from being mixed into your session.
Quick answer: open the Blackbox Tycoons experience, build one base with your partner, follow its upgrade prompts, unlock equipment, and evolve from the Caveman Era toward a future space world.
The overall loop and named endpoints come from the official description. A precise button order, prices, item stats, solo behavior, and the exact save boundary still require a documented current-game test.

The official description presents this as a two-player tycoon. Coordinate with your friend before making progress so both of you are following the same shared-base plan.
The Caveman Era is the officially named starting point. Use the buttons and prompts visible in your current session; this guide does not invent a fixed purchase order that has not been tested.
Building and upgrading are the confirmed progression loop. Before each choice, agree whether your immediate goal is more base progress or trying something newly unlocked.
The official description names gear, weapons, and upgrades as unlocks. Their exact names, prices, damage, and order are not stated in our first-party source set, so verify those details in your session.
The official description names a future space world as the destination. It does not publish every intermediate era in the sources reviewed here.
The official description says progress saves, but does not define which purchases, items, or shared states persist. Before leaving, note what you have, then compare after rejoining instead of assuming everything is retained.
A simple coordination rule is enough: one player reads the next visible option aloud, the other confirms whether it supports the current goal, and both reassess after the purchase. This is a teamwork suggestion—not a hidden game mechanic.
First confirm both players opened the same Blackbox Tycoons place and are in the same Roblox server. Then follow the current in-game prompts. We have not documented a universal join-base button sequence, so a device-specific sequence would need a fresh test.
Compare the state before and after rejoining: base progress, unlocked equipment, and any other visible state. The official phrase “Saves Progress” does not tell us which of those categories persist or whether both partners save the same state.
Stop and compare its Roblox creator and place ID. Search results can mix multiple experiences with similar names. Use the live UI and this guide's identity page before trusting the instructions.
Do not assume you missed it. Check whether the claim is about this exact experience, then review our codes status and its in-game verification boundary.
The official description frames the experience around two players, but the sources reviewed here do not define what a solo player can or cannot complete. That needs a current-game test.
We do not yet have a measured route with recorded prices and timings. Follow current prompts and choose around one shared goal rather than relying on an invented “fastest” order.
The official description only says progress saves. It does not state that every weapon, purchase, era, or partner state is retained.
Our first-party source set names the Caveman Era and a future space world, but does not provide a complete intermediate list.
