U4GM Where to Crack Arc Raiders Dam CAZ Four Button Puzzle
-
I keep seeing people treat the Controlled Access Zone like it's just another "free loot" stop, but it's more like a team check with guns pointed at you. If you're chasing better kits and comparing ARC Raiders Items with your squad, this is the spot that'll humble you fast. It sits on the Dam Battlegrounds, southwest of the Power Generation Complex, and the terrain around the dam is a pain on purpose—lots of height changes, tight walkways, and angles that punish sloppy movement.
Getting In and Powering Up
First thing: don't waste time poking the big secured door when you see it. You'll notice four indicator lights sitting there, dead and dark, like they're judging you. The safer entry is usually from below—broken grates, ladder climbs, and those lower paths where you can stay out of sight for a bit. Down there you're looking for a Fuel Cell. It's heavy, it slows you, and it makes you feel like a walking donation box. Haul it back upstairs and slot it into the power terminal. That's what wakes the place up and cracks open a side room with the first button you'll need.
The Four-Button Problem
This is where squads start arguing. The remaining buttons can spawn in different places, and you'll end up checking catwalk corners, under stair runs, and beside huge pipes like you're doing chores. The gimmick is simple and brutal: all four buttons have to be pressed at the same time. Not "close enough." Not "within a beat." Same moment, or it resets and you do the whole lap again. Most teams handle it with clear callouts and one person leading a countdown. If you're short a player, you can try to brute-force it by running between two nearby spawns, but that's usually how you get jumped mid-sprint.
Fixing the Panel and Holding the Area
When the door finally opens, it doesn't pay out instantly. Inside is a wrecked control panel that wants materials before it'll cooperate. A lot of runs ask for Metal Parts and an Industrial Battery, but the list can swing—Wires, ARC Power Cells, even a Leaper Pulse Unit if the game's feeling mean. The smart move is to plan for it: either bring likely components in, or sweep nearby buildings before you commit to the button sync. Also, assume the whole puzzle is a dinner bell. The noise and the time spent rotating positions makes it easy for another squad to set up outside and wait you out.
Loot, Extraction, and the Smart Shortcut
Once the repair's done, the vault opens and the rewards are worth the hassle—premium weapon crates, rare gear, and that "okay, we're back" feeling after a rough raid. Still, don't stand there sorting attachments like you're in a menu. Grab, split, and move. Pick an exit before you open the place, and don't all funnel through the same choke. If you're trying to gear up faster between attempts, some players top off essentials by buying items or currency through services like U4GM, then save their in-raid time for the risky puzzle runs and cleaner extracts.
