Description

𝐀𝐓𝐎𝐌𝐈𝐂𝐀 "It's Vault 33 for you and me!" On 2077, a Great War erupts, a bomb drops on Los Angeles, intending to kill everyone. Though, some do survive. Their fates are tragic. But those smart enough to be enlisted into the Vaults were able to survive without any issues. What will you do in Vault 33? Will you rebel, or obey? Atomica is a session roleplay group where the game opens during certain sessions, guided by a Session Supervisor. We have Episodes which are small fragments advancing the plot, and we have Acts - sort of like a season to a show. Each act is a fresh slate. Wondering how to get to "Vault Dweller"? It’s simple. Just join our communications and ensure you’re in the group with the "Denizen" role. After that, head to #claim-dweller to see how!

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
