Counter Strike Online Wiki

SymbolGanymede or Metus or Siege Type Deimos is a playable zombie character in Counter-Strike Online exclusive to Zombie: The Mutation, Zombie: The Hero and Zombie: The Union. It appears as AI-controlled mini-boss in Zombie Scenario.


According to the Aegis research data, it is classified as a Siege-type Deimos, and is called as an alias Ganymede separately. It is very threatening because it has strong physical strength and agility to penetrate human beings through shootings that are optimized for human infection. It has a skill to rush towards humans.

The Ganymede has the same speed and strength as Deimos but with different skill set.

Its [Charging] skill allows it to break through enemy fortifications easily by nullifying any stun received from enemy gunfire at the cost of movement speed.

It is also harder to be knocked back but not as hard as the Heavy zombie. When falling from the upper level to the lower level inside the warehouse of Assault, it does not receive fall damage.

After the Zombie Mode Rework patch, the [Hardening] skill is added (5 by default), which regenerates a certain amount of Ganymede's lost armor points.

Zombie Union[]

Ganymede has 3000 health points and 400 armor points (3500 health points and 450 armor points with Strong Lifepower). Ganymede's skill not only increases its speed, stun resistance and defense but also increases its damage by 100%. This damage increment stacks with 3x Damage, giving him a whooping 6x Damage if both skills are used at the same time.

Zombie Scenario[]

Ganymede was introduced the first time in Cube as a mini-boss. Later, it appears in most chapters of Zombie Scenario. It has 16,000 HP.

It also appears in extra chapters as the boss in Round 2, which has 100,000 HP. The players must defeat it to go to Round 3. Ganymede can do 'rush' skill, similar to Phobos. The skill will kill any human player hit within the dash range.
