Gutter Runner

The Gutter Runner (also known as the Assassin Rat) is one of the Enemies in Vermintide 2.

Description
Gutter Runners are masters of stealth, soft-footed agents of Clan Eshin who wear the shadows as a cloak. They seldom attack head on, preferring to catch a foe unaware, or else while bogged-down in combat with Clanrats or Slaves. When the Gutter Runner judges the time to strike has come, it leaps, bearing the foe to the ground, slicing and tearing at the prone victim with warpstone-edged claws.

Yet for all its cunning and ferocity, the Gutter Runner is no less a coward than others of its kind. Should it be caught in the moment of attack, or sighted out of its hiding place, it vanishes in a cloud of smoke, nimbly skirting the confused attacker as it returns to the shadows. From there, the Gutter Runner sharpens its blades and plots its assault anew, just waiting for opportunity to arise.

Strategy

 * Whenever a Gutter Runner is spotted, tag the runner as soon as possible. This is especially important during horde attacks and when your party prepares to engage a patrol.
 * Keep in mind that the Gutter Runners are the most mobile of any enemy in the game, as even without leaping they can cover impressive amounts of distances in just a short time.
 * Unlike their Moulder bretherns, the Gutter Runners of Eshin are completely immobile once they've successfully pounced one of your teammates. Take this opportunity to either push the Runner of your ally, or kill it and avoid letting it happen again.
 * Gutter Runners play an animation before they actually start to leap. If the Runner is close enough to you, use this moment to quickly take them out before they even have a chance to leap.
