Mission : Surface

BACKGROUND

A spy satellite has detected increased levels of activity at on old observatory complex near Severnaya (62.08n, 102.58e) in Russia. Other sources have confirmed the shipment of a large amount of computer hardware to that location, and an influx of skilled personnel.

M BRIEFING

It might be coincidence that there is a now head of the Soviet Space Weapons Division, your old friend General Ourumov, or it might not. Penetrate the base and find out whet is going on. Building plans for the underground section would be ideal. They're unlikely to be just lying around so look for a safe - there's bound to be someone you can borrow a key from.

Q BRANCH

I've looked over the moon photographs and I advise you to stay clear of the main bunker entrance by the helipad. However, there seems to be a ventilation tower nearby which would make an excellent spot for a covert entry. You ought to power down the comms dish too, no point in letting them tell the whole of Russia you've dropped in.

MONEYPENNY

Its cold in Siberia, James. Make sure you wrap up warm and take care to protect your extremities.
