Post-Covenant War conflicts


The Z-520 Encounter-Mitigation System,[1] known simply as the Splinter Cannon or Splinter turret, is a Forerunner weapon that saw use during the Forerunner-Flood War and centuries later by Promethean Soldiers at the outset of the Created Conflict. It fires a wide projectile that releases multiple small explosives upon impact that will explode shortly after.[2]


Used by Forerunner forces serving in Builder Security during the Forerunners' war with the Flood, the Z-520 Splinter Cannon fires unstable light mass projectiles that break apart on impact, releasing reactive fragments. This design devastated massed Flood infection forms. Seemingly designed for use in quick-reaction and expeditionary military strikes, the Splinter Cannon can either be physically moved to a site by Soldier constructs or instantly called in to reinforce a position by use of a translocation beacon. UNSC forces have only encountered the weapon paired with a generator pedestal, but it is possible there are vehicle-mounted configurations.[1]

Absent from use during the conflict on Requiem for unknown reasons, the Splinter Cannon is one of many long-lost weapons that Cortana has reclaimed from the Forerunner archives on Genesis.[1]
