The Flux Rifle is available upon reaching Aquatos from a vendor for 75,000 bolts. With use, it can be upgraded to the Splitter Rifle, and in challenge mode, it can be upgraded to the Mega Splitter Rifle for 340,000 bolts.
The Flux Rifle is a long, thin, dark green, and orange rifle with a small yellow scope, a small magazine, and a left-hand grip. The Splitter Rifle is an orange, yellow and black rifle with a slightly larger nozzle and magazine. Both rifles have a thin stabilizer mounted onto the barrel.
The Flux Rifle fires a single, powerful bullet that deals heavy damage at a long distance. It is most effective and stronger when aimed down its scope, allowing it to be precisely aimed, and also to defeat enemies at a distance from a vantage point. This can make it a very strategic weapon. However, when used without its scope, it is ineffective against all but large targets, as it can easily miss, and it is nigh-impossible to aim the weapon at enemies mid-combat without taking damage first or using the Holoshield Glove. This makes it a niche weapon.
When used strategically, it can be effective at destroying larger enemies from a distance before even engaging them in combat, reducing the threat before going in. At V4, its shots explode. At V5, it upgrades to the Splitter Rifle, which can be fired through enemies. These upgrades make it very effective when fired at clusters of enemies, although there is generally little use for the phase-through effect.
Behind the scenes
Galactic Ranger Cora Veralux designed and built this high-powered sniper rifle while simultaneously doing her math home work and eating breakfast. It was banana chocolate-chip pancakes, in case you were wondering.
