Delta Force is a game that thrives on secret loot and hidden locations, and Zero Dam is no exception. Packed with secret crates and hidden rewards, the map offers a treasure trove for players who know where to look. Whether you’re on Easy or Normal difficulty, exploring Zero Dam can lead to some fantastic finds, from exclusive gun skins to gold gear, and even sneaky ways to score gold bars. In this guide, I’m going to walk you through all the secret crate locations and how to solve the puzzles tied to them. Plus, we’ve got some bonus secrets and Easter eggs for you to uncover along the way!
All Secret Locations and Hidden Areas in Zero Dam
The Zero Dam map features eight hidden SBC crates, packed with exclusive gun skins, gold gear, and easy ways to score free gold bars. Here’s how SBC crates work:
- There are 8 SBC crates hidden across Zero Dam.
- They include 5 gun skins and 3 gold gear items (vest, backpack, helmet).
- You must enter Operations mode (Easy or Normal).
- Locate the crates (some require puzzles), extract, and stash them.
- Once stashed, open them to claim the reward (once per account).
- Re-opening the same crate again gives you 5,000 credits instead.
- Rewards are bound (can’t be auctioned), but they can be used or sold cheap.
Here are all the secret locations and hidden areas you can find in the Season 4 of Delta Force, Zero Dam:
Hidden Item Code Sheat Sheet (for the Bunker Codes)
Also, here’s a Hidden Item code cheat sheet made by HeyImSteve, you’ll need it for some of the locations (puzzles) since the codes change daily:

SPC D1: Northeast of Zero Dam
Reward: Gold Vest
The first crate sits in the northeast corner of the map, just east of the dam. To access it, you’ll need to complete a jump puzzle. Use the yellow ladder and navigate the platforms to reach the crate in the green area. If you’re struggling with the jump, turn on the automatic airborne mantle setting for easier jumps. Once you’re at the crate, you’ll find a Gold Vest inside!


SPC D2: Hidden Breach Contract
Reward: Gold Backpack
For this crate, you’ll head to an underground bunker between the Major Substation and Visitor Center. There are two entrances: one near the Visitor Center and the other near the Substation. Activate the breach contract by using a radio inside the bunker. This will highlight a blue area on your map. Head to this new location, breach the door, and defend against AI bots. Once done, you’ll get a crate with a Gold Backpack inside.


SPC D3: Key Card Chain Mission
Reward: Gold Helmet
This crate is a bit trickier. It involves a key card chain starting at the western construction site. Find a building with a beeping door and decode the Morse code (or use the clues around the building) to unlock it. After you’ve got the first key card, head southeast to a bunker, then use that key card to grab another. Continue this process until you reach the Major Substation for the last key card. Use that to unlock the final door, where you’ll find a crate with a Gold Helmet.


SPC D4: Construction Bunker Puzzle
Reward: K416 Skin
Located in the northwest construction area, this crate requires a four-digit code to open the door. The numbers are scattered across the map: one on the door itself, one in a tunnel north of the construction area, another near the admin building, and the final one on the side of the admin building. Once you have all four numbers, head back to the door and open it to reveal the crate containing a K416 skin.


SPC D5: Breach Mission Bunker
Reward: P90 Skin
This crate is hidden in the same bunker as SPC D2. Go prone and crawl under a door to reveal a secret area with a puzzle. You’ll see a keypad with a code that corresponds to flags on the Warfare mode of the Cracked map. Find these flags in Warfare, decode the Morse code, and enter the numbers into the keypad to unlock a crate containing a P90 skin.


SPC D6: Northwest Tunnels
Reward: M16 Skin
Located in the northwest tunnels, this crate is easy to spot and contains an M16 skin. You’ll find it sitting on the ground, making it a quick and simple grab.

SPC D7: Underground Cement Plant
Reward: QJB 2011 Skin
Head to the underground cement plant area near the center of the map. There’s a vent that leads to the crate. This crate contains a QJB 2011 skin, and it’s a nice reward for exploring this hidden part of the map.


SPC D8: Admin Building Underground
Reward: CL19 Skin
The final crate, SPC D8, is tucked away in an underground room beneath the admin building on the north side of the map. Look for a crate next to a large map on the wall. Open it to find a CL19 skin.

Bonus: David Room Keycard
Not a loot spot, but worth mentioning! There’s a hidden David Room on Zero Dam that you can access using Vyron. This Easter egg is more about the cool dialogue with David (aka Uluru). The door may be removed in future updates, but it’s a neat spot to check out.
Bonus: Bank Vault Gold Bars
Keep an eye on the intro sequence as you load into the map. If you see planes and rockets, the bank vault will be open. Head underneath the dam into the vault, where you may find gold bars worth 300k each. If you miss the intro sequence, don’t worry, the vault will be locked. However, triggering the Wall Breaker mission can open the bank, and you’ll be able to raid the vault for more loot.

Wrap-Up
And that’s a wrap on this guide to uncovering every hidden gem Zero Dam has to offer in Delta Force! From rare skins like the Gold Vest and K416 to the thrill of cracking secret codes and solving challenging puzzles, this map has no shortage of rewards.
I’ve had my fair share of hunts on Zero Dam, and while it can get tough, especially when other squads are gunning for the same loot, there’s nothing like the satisfaction of unlocking the K437 Assault Rifle and the 725 Double Barrel Shotgun (you can only get them in Zero Dam) or finding a rare skin tucked away in a secret crate. So, grab your gear, rally up your squad, and start exploring every corner of Zero Dam!
