Special Abilities

Cascade Effect (Ex): Once the T-S Seeker takes enough damage to be destroyed, it will automatically detonate, inflicting the damage listed under explosive.

Explosive (Ex): The T-S is programmed to explode if it comes into contact with more than 3 resistance fighters. It will attempt to ‘sneak’ up unseen, and once it is in the area of effect, it will detonate. The T-S seeker has an explosive radius of 20 ft., and inflicts 2d6+4 Plasma damage. The unit is destroyed in the process.


These small and primitive robots were created due to how resource-friendly and easily deployed they turned out to be. Each T-S Seeker is the size of a basketball, and it made of dull-grey metal. They have a single red eye-like indentation, which is also the small robot’s actual ranged weapon. They typically float just above the ground, but are fully capable of flight. There is no actual height limit, although none have ever been encountered above 30,000 feet.

Often these are sent in as scouts, but for the most part Skynet uses these cheap and easily produced models to overwhelm resistance bases or lines. The downside is that the units – designed to explode upon contact with more than 3 enemy fighters – tend to blow up when they take damage. As such, any other T-S seekers caught in the blast radius could easily detonate as well.

This is known as the cascade effect and Skynet has taken time to upgrade the primitive programming of these units so that they keep at least 20 feet between each other. This does not always work out, especially if the units are travelling through an installation, or through urban locations.

Still, the benefit of these cheap, disposable units mean that often Skynet will send out huge swarms of them to over-run resistance lines. Even if many are destroyed by enemy fire, or the death of their fellow units, more than enough often make it through to the enemy fighters to maim or kill them.

Strange as it sounds, the units are able to use their ‘sensor-eyes’ as a ranged weapon. They can fire small bursts of plasma energy at any target within 50 feet, although they rarely use this ability – after all they were created to swarm and detonate, which causes significantly more damage.
