Invader (Borderlands 2)

The Invader is a Sniper Rifle manufactured by Hyperion.

Special Weapon Effects
Fires a burst of 5 rounds when scoped, automatic stabilizes during usage of the scope.

Trivia

 * While the Invader's special effect on its own is rather common (seen on most Dahl weapons) due to the fact that it's on a Hyperion rifle, the burst becomes more accurate and more stable as the burst moves through its 5 round cycle. Thus making the last round out of the burst most accurate, vs. other burst fire weapons that become less accurate throughout the burst.
 * The flavor text references the original Invader sniper rifle in Borderlands. This was supposed to be called the "Executioner" and ended up with the wrong title due to a code bug.
