ARC Raiders keeps growing with new updates, new threats, and new reasons to head back into the Rust Belt. The Flashpoint update launched on March 31, 2026, and it added several important features, including the Close Scrutiny ARC Operation, the new Vaporizer enemy, and the High-Gain Antenna player project. This project ties directly into the new update content, so it is one of the best ways to understand what Flashpoint is trying to push players toward.
Some ARC Raiders players like to stay up to date with every patch, every project, and every reward, but not everyone has enough free time to grind everything themselves. That is where our ARC Raiders High Gain Antenna Boost can help. If you want to keep up with the game while saving time, you can also use the coupon BLOG15 for 15% off.
What is it?
The High-Gain Antenna is a new player project introduced in Flashpoint (See our Flashpoint Guide for details). In the game’s story, Celeste and Shani need help gathering resources to build an antenna that can track the strange signals and shapes appearing in the sky. In gameplay terms, that means collecting specific materials during raids and turning them in through the project system to unlock rewards stage by stage.
This project is important because it is not just a side activity with random loot. It is built around the new update loop. The same patch that added the High-Gain Antenna also added Close Scrutiny, Assessors, and Vaporizers, and those are directly tied to the materials you need in later stages. That makes the project a clear part of Flashpoint progression rather than something separate from the patch.
How the High Gain Antenna Project works
The project has three stages: Sturdy Base, Data Logger, and Parabolic Dish. You complete them by donating the required materials for each stage. As you finish a stage, you immediately unlock that stage’s rewards. There is no extra final grand prize beyond the rewards attached to each stage.
One useful detail is that you can start gathering later-stage materials early and keep them in your stash before you officially reach that stage. That matters a lot here because the project gets much harder in stages two and three, especially once you need materials from Close Scrutiny.
Stages and rewards
The High Gain Antenna Project is split into three stages, and each one has its own material requirements and reward set. The table below makes it easier to see what you need for each step, what you get in return, and where the project starts to become more demanding. It is also a good way to spot the real late-game bottlenecks, especially if you want to prepare materials in advance.
| Stage | Required materials | Rewards | Notes |
|---|---|---|---|
| Sturdy Base | 50 Arc Alloy 10 Arc Flex Rubber 10 Arc Performance Steel 15 Advanced Arc Powercell | Torrente II Extended Medium Mag III Extended Barrel Padded Stock | This is the easiest stage. Most of these materials come from ARC enemies, while the rarer parts are more common from higher-tier ARC. |
| Data Logger | 15 Arc Coolant 15 Arc Thermo Lining 4 Vaporizer Regulator 6 Assessor Matrix | Bobcat III Extended Light Mag III Vertical Grip III 100 Raider Tokens | This is where the project starts to feel like real Flashpoint content. Vaporizer Regulators come from Vaporizers, and Assessor Matrixes come from Assessors in Close Scrutiny. |
| Parabolic Dish | 10 Surveyor Vault 20 Arc Synthetic Resin 15 Vaporizer Regulator 18 Assessor Matrix | Vita Spray Photoelectric Cloak Snap Hook 400 Raider Tokens | This is the hardest stage by far. The biggest bottlenecks are Vaporizer Regulators and Assessor Matrixes, which are tied heavily to late-project farming. |
The late-game grind is mostly about Vaporizer Regulators and Assessor Matrixes. Across stages two and three, you need 19 Vaporizer Regulators and 24 Assessor Matrixes total. Those same stages also give the biggest rewards, including Snap Hook, Photoelectric Cloak, and 500 Raider Tokens in total.
Why Close Scrutiny matters so much
If you want to finish this project efficiently, you need to understand Close Scrutiny (Check our ARC Raiders Close Scrutiny Guide for details). This is a new ARC Operation map condition added with Flashpoint. It is a major map condition built around the Assessor, with less general loot on the map but valuable rewards tied to the event itself.
On exterior maps, Assessors spawn periodically, locked doors are inactive, the map has a decreased amount of overall loot, and there is an increased amount of ARC loot. That trade is exactly why this mode is so important for the High-Gain Antenna project. You give up some normal loot flow, but you gain access to the resources that matter most for project progress.
Assessors, Vaporizers, and the real bottleneck
Assessors are one of the main reasons the project takes time. They are large three-legged landing platforms that start appearing during Close Scrutiny raids. When they land, they emit red beams, and each one has three breachable containers you can loot. Those containers can contain ARC materials, the Assessor Matrix, and even the Dolabra blueprint.
The problem is that breaching an Assessor is dangerous. Triggering it sets off an alarm, which alerts nearby ARC and can spawn even more, including Vaporizers. Other players can also hear the alarm, which means you are often fighting both PvE pressure and PvP risk at the same time.
Vaporizers are the other big wall. They were added in Flashpoint as a new flying ARC enemy known for its laser attacks, and they are one of the main sources for Vaporizer Regulators. Since you need so many Regulators in the later project stages, these enemies become one of the main reasons the project slows down.
How to get the most out of it
The best way to take the most from this project is to treat it like a long grind with a clear plan.
First, save useful ARC materials early, even before you reach the next stage. Since later-stage collection can begin in advance, there is no reason to throw away materials you know the project will ask for later.
Second, prioritize Close Scrutiny whenever it is available. That mode is the center of the project because it gives you better access to Assessors, Vaporizers, Surveyors, and more ARC-focused loot overall.
Third, bring a loadout that is actually built for heavy ARC pressure. Current guidance recommends strong weapons and plenty of healing, and it also notes that the mode is much easier with a coordinated team. For Assessor runs specifically, tools like smoke grenades and the Photoelectric Cloak can help with safer breaches and cleaner escapes.
Finally, be realistic about the value of the rewards. This project is worth doing most for players who want the stage rewards, the Raider Tokens, and the satisfaction of keeping up with the patch. If you are a completionist or you want the utility items from the last stage, it is a very good project. If you are short on time, it can feel heavy, especially because the hardest materials are locked behind Flashpoint’s most punishing content.
Conclusion
For many players, the High Gain Antenna Project is really worth it. The project gives you a strong mix of weapons, attachments, utility items, and 500 Raider Tokens in total from the later stages. More importantly, it pushes you into the core content of the Flashpoint update, so it is one of the best ways to engage with what is new in the game right now.
At the same time, it is clearly not designed as a quick and casual objective. The later requirements are demanding, and the most important materials come from dangerous content with strong ARC pressure and constant risk from other players. If you go into it with a plan, though, the project is much easier to manage.
Some players want to keep up with every new ARC Raiders project and reward, but real life does not always leave enough time for long farming sessions, risky raids, and repeated Close Scrutiny runs. If you want help keeping pace with Flashpoint, our ARC Raiders High Gain Antenna Project Boost can make the process much easier.
