Trap

Trap (zs_trap) is the third chapter of Zombie Scenario: Season 1 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 and 121 minutes. 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 Andre's Diary which can be combined with other items to get special items (Note: those items cannot be obtained anymore after Zombie Scenario Re:boot. Instead, the players will receive the new ones).

Official description


Defending the construction site was not easy and our barriers have been destroyed at their hands and soon they will kill us slowly. A huge shriek and a blaring sound shook the earth just as we thought everything was over, causing the Zombies to stop their attack.

The sound echoed again, but we could grasp the words this time. The sound echoed again, but we could grasp the words this time. A voice calling himself “Rex” told us an unfamiliar story. While we did not know who he was, we understood that he was the perpetrator of this case and capturing him would enable us to secure our freedom.

I gathered the survivors to the entrance of the rooftop- which was the source of the sound. There was to be no more delays. It's time to finish everything by entering the rooftop.

- From the advance unit commander Andre's note found by the rescue team.

Rounds and tactics

 * Always run when playing this map because if you stand still, the green zombies can hit you with grenades.
 * Focus on upgrading health level but never forget to upgrade your attack power instead. Use the ratio of 2:1 where 2 is health level while 1 is attack power.
 * It is recommend to move in the same direction, so that clashing with zombies and other players can be avoided.
 * Make sure to use any machine guns and avoid using any other weapon types. Using Skull series, Balrog series, Janus series, Black Dragon Cannon, Milkor M32 MGL and AT4-CS are most effective.
 * Buy M79 Saw off or Balrog-I for emergency purposes and always recover Kevlar and Helmet.
 * Play this map from Round 1 and avoid joining the game when there is higher than Round 5 unless you possesed one of the items given by Dr. A's Trunk.
 * Prior to play in less than 4 players as this map is very small.
 * Remember to always buy HE Grenade as this is really useful when you are trapped by the zombies.
 * Be prepared to spend 1 hour 55 minutes to complete all 50 rounds.

Round 21 ~ 30

 * Round 21: Bonus round, only Pierrots spawn.


 * Round 22: Host Heavy Zombies and Host Voodoo Zombies appears. Kill the Voodoos as a main priority as they award more money than Heavies and prevent them from recovering another zombies'heath. Watch out for traps released by the heavies.


 * Round 23: Host Regular zombies spawns behind the window grates. A player should boost a teammate with a Skull-9 so that none will pass the grates.


 * Round 24: Normal Regular, Host Regular and Throw Type zombies appeared. This round is moderate in difficulty. Always stay mobile to avoid from Zombie Grenade.


 * Round 25: 2 pursuer-type Light zombies (purple colored) appears, which have high HP and damage. Players should avoid them altogether, running in circles is much more preferred. A full team armed with Balrog-XI however can make a quick work out of them, however.
