Official description

 * 30 March 2011

A huge shriek and blaring sound shook the earth and sky and threw you and the Zombies off balance. The sound echoed again and this time you’re able to grasp the words.

A voice calling himself “Lex” tells you an unfamiliar story. You, along with the other survivors, understood that Lex would be the key to freedom and rushed to the rooftop immediately.

Get ready for the bad-ass Survival mode of the Trap.
