The Antimatter Rifle fires an accurate shot with high projectile velocity that can hit multiple enemies if lined up. As a Maliwan weapon, it always deals elemental damage and can deal large amounts of status effect damage.
All damage dealt is generally multiplied by x2, including critical hit damage, status effect damage and Overkill damage – similar to a fully charged Proton Rifle. Thus, actual damage output is much higher than the stats on the card suggest.
The Antimatter Rifle's main disadvantage is its ammo consumption of 3 ammo per shot, necessitating a steady supply of ammo and frequent reloads.
