Trap

Trap (zs_trap) is an official Zombie Scenario map in Counter-Strike Online.

Overview
Trap is a very tiny map. The players are spawned in the middle of the map, on the rooftop and being surrounded by other buildings. The players must engage the zombies coming from all sides of the map in 50 rounds. There are no camping areas in this map. The number, health point and type of zombies increase as the level increases. There are bonus rounds in Round 11, 21, 31, 41 and 49 in this map.

The players who have completed Trap will receive Andrey's Diary which can be combined with other items to get special items.

Official description
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 “Rex” tells you an unfamiliar story. You, along with the other survivors, understood that Rex would be the key to freedom and rushed to the rooftop immediately.

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