The Cold Snap weather event completely transformed the economy of Embark Studios' extraction shooter. When a server spins up a Cold Snap match, ambient loot value modifiers surge, and general blueprint drop rates spike across all maps. For instance, casual and hardcore players alike have documented pulling anywhere from 6 to over 12 standard blueprints in a single 30-minute run.  
However, the ultra-rare Tempest Blueprint—the holy grail recipe required to craft some of the most dominant endgame gear—remains a stubborn exception to the rule. Historically, the Tempest has a hard-coded reliance on Night Raid map conditions to drop reliably. During a standard night rotation, the blueprint has an abysmal base drop rate of roughly 0.15% to 0.45% from generic containers. When a Cold Snap event overrides a standard match, tracking down this specific recipe requires a highly deliberate, mathematical approach to your farming routes.  
If you are tired of dealing with brutal drop percentages and want a guaranteed shortcut instead, you can always bypass the RNG grind entirely: head over to U4N to buy rare arc raiders blueprints safely and skip the tedious container loops.
Best Farming Locations During Cold Snap
While a Cold Snap event mathematically inflates the general loot table pool by adding extra rolls to every container, it does not automatically spawn the Tempest Blueprint in basic weapon cases. To find it, you must ruthlessly target high-density residential containers—such as drawers, cupboards, and suitcases—which possess the specific item tags that can trigger a Tempest drop.  
1. Buried City (The Gold Standard)
Buried City remains the absolute best map for a Cold Snap blueprint run due to its vertical residential architecture.

• Grandioso Apartments: This is the highest-volume farming zone in the game. It consists of two massive apartment towers in the West Village connected by a makeshift bridge. Every single floor is packed with drawers, cabinets, and dressers. A thorough sweep of both buildings offers over 45 high-tier residential container rolls in under five minutes.  
• Plaza Rosa Pharmacy: Locate the three-story medical building near the extraction point. Blow through the breachable door and skip the open metal shelves on the first floor. Instead, sprint to the second and third floors to empty the white medical cabinets and employee lockers.  

2. Stella Montis

• Town Hall: Bring a pink keycard to access the secure upper offices. The desks and filing cabinets inside have a concentrated drop rate modifier during weather events.
• Medical Research Wing: Focus your route exclusively on the rear locker rooms. The wall lockers here have a secondary chance to roll the blueprint alongside high-tier healing items.

3. Spaceport

• Shipping Warehouse: Check the stack of blue and orange cargo containers on the eastern tarmac.
• Departure Building: Navigate to the upper office desks. While highly contested by PvP squads, these desks provide an excellent fallback if Buried City is locked down.

Optimized Farming Strategy: Maximizing Containers Per Hour
Because the absolute drop rate of the Tempest Blueprint sits firmly below 0.50% even with the Cold Snap event multiplier active, your success relies entirely on volume. If you open 10 containers a match, you will likely never see it. If you open 100 containers an hour, the math swings in your favor. Use this three-step efficiency loop to maximize your runs:

1. Go Completely Naked (The Budget Strat): Drop into the match completely unequipped or carrying nothing but a bottom-tier pistol. Entering a raid with zero gear value automatically guarantees a dedicated Safe Pocket slot. If you unearth the Tempest Blueprint, it goes straight into your Safe Pocket. Even if an ARC machine or a hostile player guns you down a second later, the blueprint remains yours permanently.  
2. Infiltrate Squad Lobbies Solo: Queue by yourself directly into trios or squads matchmaking. Squads entry completely changes player psychology; multi-man teams almost always hunt high-tier PvP engagements, world bosses, or major extraction vaults. They will walk right past residential areas like the Grandioso Apartments, leaving dozens of drawers completely untouched for a solo rat to clean out.
3. The 90-Second Fast Reset: Efficiency is defined by your "containers-per-hour" metric. If you spawn on the far edge of the map, hundreds of meters away from a primary residential zone, do not waste 10 minutes trekking across the terrain. Open your menu, hit surrender, and re-queue immediately. Your goal is to maximize spawns that place you within a 60-second sprint of a major apartment complex.

Alternative Methods to Bypass the Grind
If the random number generator refuses to cooperate after dozens of naked cycles, the Arc Raiders community has established reliable alternative economies.
First, check the player-driven Metaforge Database Market. This web platform acts as a community escrow where players list verified blueprint drops for direct trade. If you have collected duplicate weapon attachment blueprints during your Cold Snap runs, you can easily find a player willing to swap a Tempest recipe for multiple lower-tier weapon mods.
Second, save up your in-game currency. High-level endgame NPC traders occasionally cycle the Tempest Blueprint into their rotating stock. Be warned: it comes with a massive 1,000,000 credit price tag. If you choose this route, utilize the Cold Snap event to hoard high-value junk items like Portable TVs and circuit boards, selling them in bulk to build up your bankroll.
