The A-07 Complex and Catacombs are two of the most rewarding loot locations in Havoc. If you bring the right keycards and follow an efficient route, you can clear both areas in a single raid and walk away with valuable weapons, armor, safes, and military crates. This guide explains the recommended route, required keycards, and important survival tips to help you complete the run successfully.
Recommended Gear Before Entering
Before attempting this loot run, it’s recommended to bring:
- Tier 4 Keycard
- Tier 5 Keycard
- Tier 6 Keycard
While it’s possible to complete the route with only a Tier 6 Keycard, having all three cards lets you access more locked rooms and maximize your profits.
You should also bring:
- Plenty of inventory space
- Two stacks of lockpicks
- Reliable armor and weapons
- Medical supplies
Since you’ll be opening multiple safes and locked containers, running out of lockpicks can force you to leave valuable loot behind.
Don’t Waste Armor on Face Shields
One useful tip before entering the raid is to avoid using your armor durability on face shields whenever possible. Face shields lose durability quickly and generally provide less value compared to preserving your armor for direct firefights.
After entering the A-07 Complex, begin clearing the first rooms while watching for AI enemies. Sometimes enemies group together and rush through the entrance, making them easier to eliminate. Other times they’ll spread throughout the facility, requiring a much slower and more cautious approach. Clear nearby threats before focusing on loot.
Search Every Small Container
While military crates and safes provide the best rewards, don’t ignore smaller loot containers.
These boxes can contain valuable items, including:
- Gold Bars
- Medical supplies
- Lockpicks
- High-value crafting items
Small containers are quick to check and can significantly increase your profits.
Visit the Tier 5 Room
One of the main stops during this route is the Tier 5 Keycard room.
Inside you’ll find:
- Multiple loot crates
- A safe
- Additional storage containers
Although the room doesn’t always produce amazing rewards, it still has the potential to contain valuable equipment and is worth opening whenever you have the required keycard.
Stay Alert While Lockpicking
Lockpicking leaves you vulnerable. AI enemies can quietly approach while you’re focused on opening safes, so always keep your camera facing the entrance whenever possible. Checking your surroundings before every lockpick can prevent unexpected deaths.
Watch Out for Turrets
Several sections of the A-07 Complex contain automated turrets. Common turret locations include:
- Hallway intersections
- Upper walkways
- Corridor entrances
Destroy each turret before moving deeper into the complex, as they can quickly eliminate unprepared players.
Gas Mask Shortcut
Some areas require a Gas Mask to access. Using one allows you to bypass certain sections of the map and reach alternative exits or loot areas. However, if you don’t regularly carry a Gas Mask, you can simply continue along the standard route without missing the majority of valuable loot.
Catacombs Route
After finishing the Complex, continue into the Catacombs. Along the way you’ll encounter:
- Additional military crates
- Safes
- Toolboxes
- Loot containers
- More AI enemies
The Catacombs greatly increase the overall value of the raid, making it worthwhile to clear both locations in a single run.
Beware of AI Patrols
The Catacombs feature several dangerous patrol routes. Some AI enemies constantly move through specific corridors, while others remain hidden until players get close. Move carefully around corners and avoid sprinting blindly into open areas.
Loot Military Crates
Military crates offer some of the best rewards in Havoc. Possible loot includes:
- High-tier armor
- Weapons
- Valuable crafting materials
- Attachments
- Backpacks
Always prioritize these containers whenever you find them.
Check Cabinets and Toolboxes
Cabinets and toolboxes are easy to overlook, but they can contain surprisingly valuable items. Possible rewards include:
- Bitcoins
- Gold Bars
- Diamond Rings
- Lockpicks
- Other rare valuables
Since they take only a few seconds to search, they’re almost always worth opening.
Best Loot Room
One of the best rooms in the entire route contains:
- Two military crates
- Multiple storage containers
- High-value weapon spawns
This room consistently offers some of the highest-value loot available in both the A-07 Complex and Catacombs.
If you’re only targeting one major room during the raid, this should be your priority.
Guaranteed Weapon Spawns
The route also provides access to several powerful weapons.
Players commonly find:
- MK-14
- SC58
The MK-14 is one of the most valuable weapons available and can also drop from the Surface boss.
Finding either weapon significantly increases the value of your run.
Skip Low-Value Areas
Not every room is worth looting. Some tunnels only contain a few basic boxes or a single safe, making them inefficient if your inventory is already full. Once you’ve collected the best loot, it’s usually better to head toward extraction instead of clearing every hallway.
Bring Extra Lockpicks
Since this route includes numerous safes and locked containers, lockpicks are one of your most important supplies. If you begin running low, check:
- Mechanic shelves
- Toolboxes
- Utility containers
These locations often contain replacement lockpicks.
Best Tips for This Route
To improve your chances of success:
- Bring Tier 4, Tier 5, and Tier 6 Keycards.
- Carry at least two stacks of lockpicks.
- Eliminate nearby AI before looting.
- Destroy turrets before advancing.
- Search both military crates and smaller containers.
- Prioritize the high-value loot room.
- Leave once your inventory is full instead of risking unnecessary fights.
Running both the A-07 Complex and Catacombs in a single raid is one of the most profitable loot routes in Havoc. With the proper keycards, enough lockpicks, and a careful approach, you can collect high-tier weapons, military gear, safes, and valuable items before extracting. While the route is challenging due to AI patrols and turrets, mastering it can consistently produce some of the best loot available in the game.
