Marathon‘s Server Slam has begun, with the full launch coming soon, and we finally have confirmed details about the abilities of the seven Runner Shells.
Every Runner Shell in Marathon has a unique playstyle that determines their respective strength and weakness. No two Shells behave in the same fashion, and all of them have unique roles, traits, and abilities. This guide will provide you with an overview of all seven Runner Shells that are currently available.
All Runner Shells and their abilities in Marathon
All Runner Shells have a Prime ability, which can be considered their ultimates. These abilities are extremely powerful, but they take time to charge up. They also have their unique traits that serve as their primary gadget. The kit is completed by two abilities or traits that are unique to all Shells.
Destroyer
The Destroyer is a great choice for beginners and serves the role of an all-rounder in a perfect fashion.
| Ability | How it Works |
|---|---|
| Search and Destroy (Prime) | Activate shoulder-mounted missile pods. |
| Riot Barricade (Tactical) | Toggle an energy barricade that blocks incoming damage, draining tactical ability energy over time. |
| Thruster (Trait 1) | Activate while airborne to fire boosters that thrust you in the direction you are moving. |
| Tactical Sprint (Trait 2) | Double-press sprint to move faster at the cost of generating additional heat. |
Vandal

Vandal mixes combat-focused abilities with movement buffs.
| Ability | How it Works |
|---|---|
| Amplify (Prime) | Increases movement speed and weapon dexterity while reducing the heat generation at the same time. |
| Disrupt Cannon (Tactical) | Transform the arm into a cannon that deals damage and pushes the enemy back. |
| Microjets (Trait 1) | Perform an extra jump at the cost of extra heat. |
| Power Slide (Trait 2) | Grants a supercharged slide that generates extra heat. |

Assassin

The Assassin’s primary role is to use stealth to create confusion among the opposition players.
| Ability | How it Works |
|---|---|
| Scoke Screen (Prime) | Throw a smoke disc that creates a line of smoke in front of you. |

| Shadow Dive (Trait 1) | Activate while airborne to slam a smoke disc into the ground. |
| Shroud (Trait 2) | Your cloak automatically makes you invisible when you’re entering smoke. |
