With the trailer for Doctor Who - Dark Eyes 4 premiering in yesterday's Big Finish podcast, it's time to make a few others available: the trailers for two of March's other Doctor Who releases are now online, starting with Doctor Who - The Fourth Doctor Adventures: Requiem for the Rocket Men:

The Asteroid - notorious hideaway of the piratical Rocket Men. Hewn out of rock, surrounded by force-fields and hidden in the depths of the Fairhead Cluster, their base is undetectable, unescapable and impregnable.

In need of allies, the Master has arranged to meet with Shandar, King of the Rocket Men. But the mercenaries have captured themselves a very special prisoner - his oldest enemy, the Doctor.

What cunning scheme is the Doctor planning? How does it connect with Shandar's new robotic pet? And just what has happened to Leela? The Master will have to work the answers out if he wants to leave the asteroid... alive...

The trailer for Doctor Who - The Fourth Doctor Adventures: Requiem for the Rocket Men can be heard by visiting the story page through the link, and the release can be pre-ordered now, either as a single release, or as a Series 4 Subscription, or Bundled with the much-praised Doctor Who - Philip Hinchcliffe Presents...

Today's second trailer is for next month's main range title, Doctor Who - The Entropy Plague, which ends the most recent run of Fifth Doctor, Nyssa, Tegan and Turlough stories:

A Great Darkness is spreading over E-Space. Entropy increases. In search of a last exit to anywhere, the TARDIS arrives on the power-less planet of Apollyon, where the scientist Pallister guards the only way out – a mysterious portal. But the portal needs power to open, and the only power Pallister can draw on is the energy contained within the molecular bonds of all living tissue...

The Doctor, Nyssa, Tegan and Turlough soon learn that neither Pallister nor his ally, the space pirate Captain Branarack, will stop at murder to ensure their escape. But they're not the only menace on Apollyon. The Sandmen are coming – creatures that live on the life force; that live on death.

Death is the only way out into N-Space. Death, or sacrifice.

But whose death?

Whose sacrifice?
