The Arc Raiders expedition window is officially open, with departures scheduled for the 22nd, just days away. If you are anything like most players heading into a wipe, you are likely in a frantic last-minute push to extract as much value as possible from the expedition. Whether your goal is maximizing skill points, padding your wallet, or simply reducing the stress of  ARC Raiders BluePrints missing out, now is the time to act smart rather than panic.

This guide breaks down the expedition requirements, efficient farming routes, and practical mindset tips to help you make the most of the remaining time before reset.

Understanding the Expedition Contribution Tiers

While the main focus for most players at this stage is no longer completing the expedition outright, it is still important to understand how each tier works, especially if you are missing key contributions.

Tier One Requirements

    Metal and rubber parts

    Arc alloy

    Steel springs

These materials are straightforward. Arc alloy can be obtained by recycling Arc Raiders items or killing ARC enemies, while steel springs are commonly found in industrial zones or breachable containers in the open world.

Tier Two Requirements

    35 durable cloth

    20 wires

    30 electrical components

    5 cooling fans

At this point in the expedition, most players should be crafting durable cloth and electrical components in refiners. Durable cloth is most commonly found in medical zones, while wires and electrical components appear in technological loot pools. Cooling fans are typically found in large vertical breachable containers such as server racks.

Tier Three Requirements

    5 light bulbs

    30 batteries

    20 sensors

    1 Exodus module

Light bulbs can be found in lockers, cars, breachable containers, and occasionally standard containers. There is also a static spawn near the electrical substation and water towers on the Dam. Batteries come from computers, while sensors appear frequently in server racks.

For Exodus modules, the most reliable sources are Exodus-marked zones and Stella Montis' assembly area. Many pink-tier items found there are recycled directly into Exodus modules, making it an efficient farming location even if you do not find the module outright.

Tier Four Requirements

    5 humidifiers

    5 advanced electrical components

    3 magnetic accelerators

    3 Leaper pulse units

Humidifiers are most commonly found in residential zones such as Buried City, Pale Apartments, Ruby Residences, and Pattern House on buy ARCR Items the Dam. Advanced electrical components can be crafted or found in control rooms and technological consoles. Magnetic accelerators are craftable but are also common in Stella Montis. Leaper pulse units, as expected, are obtained by killing Leapers.
