Ice Breaker

 is a gun. The first two shots of each magazine fire a shotgun blast of ice bullets, and the final shot fires a single, piercing, explosive shot.

Trivia

 * "Never Let Go" references the final scene in the film Titanic.
 * This is also a reference to Destiny's IceBreaker indicated by its color and synergy with The Exotic. Its synergies with Patriot and The Exotic change its appearance to match the Destiny gun.
 * The Gunderlord synergy, which connects Patriot shots with electricity, is likely in reference to the Destiny gun Thunderlord.
