Trespasser

The Trespasser is a Sniper Rifle manufactured by Jakobs in Borderlands 2.

Special Weapon Effects
Shots bypass shields and Mordecai contacts you via ECHO to see if you're all right when getting a Second Wind.

Usage & Description
The Trespasser is a fairly standard Sniper Rifle with the exception of the ability to penetrate shields. Its damage is often lower than other sniper rifles of the same level, however, bypassing shields makes it much more effective against certain enemies. Of note is its behavior against Stalkers - because of its effect, it will be able to kill stalkers outright before almost any other sniper rifle, however, if the stalker survives the shot, its cloak is still fully effective.

Another trick one can use when carrying the Trespasser is to have it in the active weapon slot before entering a vehicle. The machine gun attacks of both the Outrunner and the Bandit Technical will then penetrate enemy shields. The Sawblades as well as the explosive weaponry remain unaffected, however.

It is also worth mentioning that unlike Mordecai's Trespass skill, which had a chance to bypass shields based on its rank, the Trespasser will always penetrate shields.

Trivia

 * The flavor text is a reference to Mordecai's "Fight for Your Life" mode quote where he screams "I NEVER DIE!"
 * The gun's name comes from Mordecai's skill, Trespass, which lets the user bypass shields.
 * It should be noted that the gun still can not bypass Master Gee the Invincible's shield.
