Snow

Oh, the weather outside is frightful,but inside its so delightful.

The minimap when snow is present.

There's no stopping this post-modernist from painting the snow.

From the update on December 10, 2007:

This year it's cold enough to snow, and it's beginning to settle. Walking outside will leave trails of footprints that last until the snow covers them - be careful about leading any unwanted visitors back to your well-hidden safehouse.

From the update on December 22, 2009:

Another cold winter in the quarantine zone, and snow is falling. Walking or lurching at street level will leave a temporary trail of footprints right to the door of any building you enter, so watch your step.

Snow is a weather effect that comes into play in December. When movement is made through the snow, a trail is left behind, including when you enter or leave a building. The message shown is as follows:

You lurch/walk through the snow, leaving a trail of footprints behind you.

If footprints have already been made, then it becomes "following a trail of footprints."

You leave the building, making a trail of footprints in the snow.

Building Description

When standing outside a building, its description is also altered. for all buildings there is the text:

Thick snow covers the ground.

If anyone has entered the block since snow covered the ground, the full stop of the previous stament is replaced by a comma and the following message appears:

with footprints entering from the x.

When x is the direction in which you travelled.

If anyone has left the block since snow has covered the ground, the previous full stop is replaced by a comma and this stament appears:

and leaving to the x.

If anyone has left the building, then the following message appears:

A set of footprints leads out of the building.

If anyone has entered the building, the stament above changes to:

Further sets of footprints lead into and out of the building.

Loose footing, Blood and Snowbanks

"Slipping" out of a tall building gives the following message:

You fall heavily onto the pavement, a few storeys below. A snowbank collapses.

If a snowbank is present, then the message is the same as normal.

If someone has fallen out of a building, then the following message appears:

A collapsed snowbank shows where someone has fallen from the building.

If someone is killed outside, the following message is shown upon the kill:

They die. Blood soaks into the snow.

The building's description changes to:

Thick snow covers the ground. It is tinged with blood.
