Walking Dead

A new promo for The Walking Dead's season three highlights critics' positive impressions of the
series -- all the while the characters encounter zombies and kill two of them.
The video, shared exclusively with Mashable, shows the zombie apocalypse survivors battling outside of a prison, where they hope to seek sanctuary because of its potential amenities: weapons, food and medicine.

Once inside the prison, they will have to fend off any remaining zombie occupants and even other humans who might already call the prison home. "The Governor," a new villain who is the leader of a small community of survivors, also might sour their plans to occupy the prison.

The previous season's finale in March became the most-watched basic cable drama ever with more than 9 million viewers. During that episode, survivors escaped a deadly zombie attack on their farm and viewers were introduced to the sword-wielding Michonne. And at the end, viewers got their first brief glimpse of the prison.

Earlier this month, AMC celebrated accumulating 10 million Facebook "Likes" by releasing a graphic that paid homage to The Social Network's movie poster from 2009. The Walking Dead returns to AMC on Oct. 14.
