GateWorld has just published a handful of photos from three more upcoming Atlantis episodes! Visit the Season Two episode guide to find the first shots from “Michael,” “The Long Goodbye,” and “Critical Mass.” Beware of minor spoilers for these episodes.

“Michael” guest stars Connor Trinneer (Star Trek: Enterprise) as the title character, a young Lieutenant who makes a shocking discovery about his true identity after waking up in the Atlantis infirmary with amnesia.

The plot of “The Long Goodbye” remains a mystery, but the show’s producers do promise that actress Torri Higginson (“Elizabeth Weir”) will see some exciting hand-to-hand combat.

In “Critical Mass,” the team suspects that they may have a traitor in their midst when a signal is sent from Atlantis to the Wraith. From the looks of the one photo now available, SG-1‘s Beau Bridges (“General Hank Landry”) will guest star.

There will be plenty more photos to come as we get closer to these episodes air dates! Keep your browser locked on GateWorld for the very latest.

New episodes of Stargate Atlantis return to The SCI FI Channel in the U.S. in January! Thanks to New Atlantis for passing along these photos.
