How to get Destiny 2 Dimensional Hypotrochoid Grenade Launcher. Dimensional Hypotrochoid is a Stasis energy, Compressed Wave Frame Grenade Launcher. You probably first encountered the Dimensional Hypotrochoid Grenade Launcher as a reward for one of the steps at the beginning of the Lightfall campaign. The rewarded weapon is also a red bar – meaning you can extract a pattern from it to be able to craft it later. After that, it’s relatively easy to get more. You can get Dimensional Hypotrochoid Sniper Rifle by completing any activity in the new Destiny 2 Lightfall Neomuna location.
