Is There a Stargate Atlantis Game on Xbox 360? No

No Stargate Atlantis game was ever released for Xbox 360 (or any console).

The Only Console Stargate Game

• Stargate SG-1: Unleashed (2005) — **PS2 & Xbox (original)**. Third-person shooter. Covers SG-1 Seasons 1–7. Mixed reviews (metacritic 55).

Stargate Games on Other Platforms

• Stargate SG-1 (PC, 2005): Different game — FPS by Perception. Also mediocre.
• Stargate Resistance (PC, 2010): 3rd-person team shooter (SG-1 vs. Goa'uld). Servers dead.
• Stargate Worlds (PC, Cancelled): Promised MMO. Vaporware.
• Mobile: Stargate: Universe (card battler), Stargate: Timekeepers (tactical, 2024, PC only).

Why No Atlantis Game?

• SG-1 was the flagship show (10 seasons). Atlantis (5 seasons) aired concurrently but had smaller budget/merch.
• License holder (MGM) licensed SG-1 only for the console game.
• Realtime Worlds went bankrupt after APB (2010) — no sequel chance.

Modern Way to Play

• Original Xbox / PS2 disc + working console.
• Xbox 360 Backward Compatibility: Stargate SG-1: Unleashed **is NOT backward compatible** on 360.
• PC Emulation (PCSX2 / Xemu): Play PS2/Xbox version upscaled.
• Stargate: Timekeepers (2024, PC): New tactical game (Slitherine). Atlantis characters? Unconfirmed.

For Atlantis specifically: watch the show. No game exists.
