I've bought and used the Phaseshift. In theory its an amazing weapon, no need to every resupply for ammo or reload and can be used as either a bolt action or semi auto. In practice its terrible, having such a long charge for bolt action damage leaves you open to being counter-sniped or just straight up shot and it has awful velocity. Its nearly impossible to hit a moving target. When using semi auto the recoil is insane, it has the kickback of a shotgun and it fires just as slowly if not slower. Essentially its a Vanu weapon, it looks awesome, and can do some cool things, but it sucks. Honestly a parallax and vandal are so vastly superior to the phaseshift that it is 100% not worth buying.
