SCP: Containment Breach Multiplayer

SCP: Containment Breach Multiplayer launched on October 25, 2021 and has maintained a steady cadence of major updates: v1.2.0 (November 2021), v1.2.9.1 (March 2023), v1.3.0.0 — the Anomaly Ascension Update (June 2024), and now v1.3R — the Foundation Update, which shipped today, October 3, 2026. The v1.3R update arrived today after approximately two years of development and is described as the largest overhaul the team has ever produced, covering engine migration from DirectX 7 to DirectX 9, graphics improvements, gunplay reworks, UI overhauls, dedicated server enhancements, and security fixes. Notably, the Halloween 2025 announcement had teased new playable SCPs (SCP-066 and SCP-457) and new factions (NU-7, GOC, Serpent's Hand) for this update — those promises now appear to have been fulfilled by today's release, or are part of the continuing rollout. The v1.3R post explicitly lists further planned major updates with no completion signal: full Lua modding support, an anti-cheat rework, and a complete multiplayer rework including dedicated and co-op servers. The developer also promises "monthly/weekly updates" going forward and introduced a public GitHub tracker for the community to follow ongoing development. These are clear commitments to continued substantial development. The store description likewise describes "frequent updates" and "an active development team," consistent with the actual update history. With a major update shipping today and the next wave of planned content already announced, this game is firmly in ongoing development with more substantial content on the way.
