Week 18 Trials in ARC Raiders add another solid mix of combat and scavenging objectives, and if you're aiming for three stars across the board, you'll need to play smart. The focus this week is on damaging Leapers, looting bird nests, taking out Spotters, opening ARC Probes, and searching containers in the Medical Research Wing. Just finishing them isn't enough if you care about rewards or leaderboard placement. Speed, clean execution, and staying alive are what really matter ARC Raiders Coins.
The Leaper trial is probably the most dangerous of the bunch. These things jump fast, hit hard, and can punish sloppy positioning. Dam Battlegrounds and certain Matriarch hunt areas tend to have reliable spawns, especially near elevators and open spaces. Using cover is key, since their leap attacks can chunk your health if you're exposed. Aim for weak spots when you can, and don't be afraid to use explosives to clear them quickly. On tougher map modifiers, you may need multiple kills for full stars, so treat it like a farming run instead of a quick objective.
Bird nest looting is a lot calmer by comparison. This one usually sends you to Buried City during active events. The nests are often on rooftops or tucked near chimneys, and they can contain small valuables that sell for decent credits. It's low risk if you stay aware of your surroundings, and you can often clear the requirement in a single event cycle. If you're already running Buried City for other tasks, this is basically free progress.
Spotters are a different story. These drones don't hit that hard themselves, but if you ignore them, they'll call in reinforcements and turn a manageable fight into chaos. They show up on multiple maps, so it's worth building the habit of scanning for them early in a raid. Mid-range weapons work well since you'll usually want to pop them before they alert nearby enemies. If you're running as a squad, call them out immediately and focus them down together. It keeps things under control and helps you avoid getting overwhelmed while chasing other objectives.
Opening ARC Probes is more about awareness than raw firepower. The upright ones are usually more valuable, but they're also noisy when activated, which attracts attention. You'll want to clear the area first, then loot fast. Since they don't have fixed spawn points, it helps to learn common high-traffic areas where they tend to appear. This objective is manageable solo, but it's smoother with at least one teammate covering angles while someone interacts with the probe.
The Medical Research Wing task is probably the riskiest overall. It sends you into Stell Montis, specifically the southwestern upper floor area that's known for good materials. That also means other players are likely heading there. The goal is simple—search containers—but doing it safely is the challenge. Move carefully, check corners, and don't get greedy if you hear footsteps nearby. Grab what you need and extract. If you're chasing three stars, time management and survival matter more than squeezing every last item out of the room.
If you're trying to maximize performance, it helps to prioritize combat-heavy tasks like Leapers and Spotters early, when your squad is fresh and fully stocked. Then handle probes and nests while rotating through maps, and leave the Wing run for when you're confident in your gear. Balanced team setups work best—good mid-range damage, some crowd control, and tools for holding choke points. Reviving teammates quickly and avoiding unnecessary fights can be the difference between a clean three-star run and a frustrating reset.
The rewards scale nicely if you perform well. Hitting three stars across the trials unlocks better credits, stronger gear drops, and boosts that help with seasonal progression u4gm ARC Raiders Coins. Sloppy time management or ignoring side objectives can cost you, but once you learn spawn patterns and tighten up communication, Week 18 becomes pretty consistent. As the game moves deeper into its seasonal cycle, staying on top of these trials is one of the easiest ways to keep your stash strong and stay competitive.
