Warframehas hundreds of unique weapons to choose from, ranging from traditional ballistic weapons to orbital cannons and throwing stars. The Riot-848 takes the familiar full-auto secondaries of conventional times and warps it with Entrati energy, allowing the gun’s spent ammunition to feed back into the magazine between reloads.
It’s an odd weapon to get used to, but it is certainly effective if you’re willing to invest Forma into it. But before you can make a good build for it, you’ll need to craft it first. This short guide will go over how to get the Riot-848, covering everything from drop rates to crafting requirements for each part.

How To Get The Riot-848
The Riot-848 is a drop from theSolstice Square Defense mission in Hollvania. You’ll unlock access to all Warframe 1999 content upon completing “The Hex” questline. Once complete, use the 1999 terminal aboard your Orbiter to view all Hollvania missions. Solstice Square is the top left node on the map.
This mission functions identically to Lua Defense, requiring you todefend Flare against waves of enemies.After the first three waves, Flare’s stage will collapse into the sewer system below. Flare will stay at this location for the rest of the mission. This area is far more claustrophobic than the surface and has more spawn locations for the enemies, leading to much faster waves if you have a strong loadout.

As for the weapon itself,Riot-848 drops from each rotation in Solstice Square.All parts can drop in each rotation (A, B, and C), although higher rotations have a higher drop chance. Remember that reward payouts go in the following order, with payouts being every three waves: AABC, AABC, AABC…
If you’re able to’t get any of the Riot-848’s components to drop,you can also purchase the blueprints from Flare directly in the Hollvania hub.Components will require Beating Heartstrings to purchase this way, a currency you’ll earn for successful wave clears. You’ll need300 Beating Heartstringsto purchase all Riot-848 components.
