Classes

Classes were first introduced in Worms Revolution. Each class has strengths and weaknesses as well as differently-pitched voices. Players can mix and match them in any order. They later reappear in Worms Clan Wars, Worms Battlegrounds and Worms 3 for iOS.

Soldier
The main class throughout the series. The Soldier is a balanced Worm meaning no strengths or weaknesses. They can manually detonate Grenades in Worms Clan Wars. Players automatically start with a full team of Soldiers. Their voices remain unchanged.

Heavy
The Heavy is a large and bulky Worm. They move very slow and cannot jump very far. However, the Heavy can fling Worms great distances when using a Baseball Bat or Fire Punch and cannot easily be launched into the air from weapons. Another drawback is when using the Jet Pack it moves slowly and runs out of fuel very fast. Heavies have a low-pitched voice.

In Worms Clan Wars, they make larger explosions and death explosions. Generally, they deal more damage. (Ex: 30 damage [standard 25] with a Shotgun.)

Scout
The Scout is a small Worm. Scouts can move faster, jump further, fly great distances with the Jet Pack and fall down large gaps without trouble. However, because of their size they are easily flung when hit with weapons, which is why caution is advised when near the water or other hazards. A unique ability is that when using a Blow Torch scouts can create a hole where other Worms can't fit through. Scouts have a very high-pitched voice. In Worms Clan Wars, Scouts can see the contents of nearby Crates at the start of their turn (similar to the Crate Spy utility from older games in the series) and can walk over Mines without triggering them.

Scientist
The Scientist is a Worm with a big brain. They have the same movement as Soldiers. Their ability is being able to grant all nearby Worms on their team 5 health each turn while alive. Scientists can also use improved versions of Electromagnets and Sentry Guns that last longer and do more damage. However, Scientists will take more damage when struck with any weapon. Scientists have a slightly high-pitched voice.
