Saboteur is a Reaper alien that has a special ability, it shoots a blue debuff orb at a players ship that dramatically decreases your speed, virtually holding you in place. An EMP will disable this effect. All further information is being investigated.
There is an interesting glitch in the game where if an enemy player shoots you and uses pet-kamikaze to strike the final blow, and if you were in the middle of jumping when you die, your ship won't explode but your health point will appear to be zero. In these cases, the kill screen will say that a Saboteur shot you down and not the enemy player's name.
Saboteurs are one of the slower pirates aliens. A Goliath with 15 G3N-7900 speed generators can easily outrun one providing the Saboteur doesn't use it's DCR attack.
Saboteurs seem to be constructed out of many different ships. For example: there is half of a Goliath's "pincer" attached to one side of a Saboteur.
