Step 1: Obtain the DRI-11 Beam Smasher

How to Craft the DRI-11 Beamsmasher

In order to start the Terminus Main Quest, players must have acquired the Beamsmasher, which is the Wonder Weapon found on Terminus Island. Players can get the Beamsmasher by getting lucky at the Mystery Box, or using the Wonderbar! GobbleGum. Alternatively, players can get the Beam Smasher by crafting it, and here’s how:

Black Ops 6: How to Get the DRI-11 Beamsmasher in Terminus

Terminus holds a unique Wonder Weapon in the form of the DRI-11 Beamsmasher for Black Ops 6 players to craft and use to destroy endless zombie hordes.

• Activate the AMPs to turn on Pack-a-Punch and the power.
• Activate three laptops, with one found outside the Storage Area, another outside Communications, and the third by the Docks after the Sea Tower.
• Purchase a Deadwire Ammo Mod and shoot that weapon at an electric circuit in the broken window on the Inclined Lift going up from the Bio Lab, and follow the circuit to other electrical boxes through to the Living Quarters,
• Enter the Research Office at the Rec Yard kill the trapped zombie and then pick up the EMF Fob.
• Enter the Sea Tower where Elemental Pop is located and interact with a briefcase that has a hand attached to it to pick up the Multiphasic Resonator.
• Interact with the computer in the Research Office, twice
• Pay Peck 5,000 Essence in the Guard Station to acquire the code that can be entered at the computer in the Research Office.
• Finish the Round, then head to the specified island marked by the computer and place the Multiphasic Resonator by the glowing orb. Kill the unlimited spawning zombies and one will glow the same color as the orb and drop a pickup which can be placed into the orb twice. The orb will fly off to a different island, so pick the Multiphasic Resonator back up and repeat the step at a new island until players can pick up the AMP Munition.
• Head back to the Research Office and hold interact on the workbench to craft the free Beamsmasher.

Step 2: Acquire the Hard Drive and Give it to Peck

With the DRI-11 Beamsmasher obtained, it’s time to acquire a Hard Drive which can only be taken from one of the tentacle traps around the map. To activate the tentacle trap, players must spend 750 Essence, and it’s worth mentioning that standing in the trap will see players pulled up, where they will be killed, so if you are grabbed, just shoot at the tentacle trap to get dropped. Either way, here’s all the locations of the tentacle trap:

• Outside the Mining Tunnels connecting to the Bio Lab
• Outside the Sea Caves connecting to the Bio Lab
• Between the Holding Cells and the Guard Station at spawn
• Inside the Living Quarters out to the Wreck Yard

To find the correct tentacle trap, check the floor of these locations for an ID badge. Once found, activate the trap and shoot the tentacles in a stream with the DRI-11 Beamsmasher’s primary fire until a Hard Drive bursts free, to which players can then collect it.

With the Hard Drive in hand, players will need to enter back to the spawn location at the Guard Station where they can see Peck and Strauss in the control room. Interact with the drop box in the Guard Station to deposit the Hard Drive which will allow him to hack the central containment unit in the middle of the Bio Lab, where Maya’s brother, Nathan, is held. Head down to the Bio Lab and interact with the central cylinder to see Nathan, and then it’s time to free him.

Step 3: Find the Codes to Nathan’s Containment Unit

How to Free Nathan in Terminus

Once players have interacted with the containment unit in the center of the Bio Lab, a mini-cutscene with Nathan will play, and now players must run around and collect three numbers found in specific locations, with a specific order, and here’s the location of each:

Nathan’s Cell Number #1

Inside the Interrogation Rooms where Quick Revive is stationed, head to the fenced South wall, noted by the bloodied chair in the middle. Look at the clock on the back wall and make note of the hour hand (short hand), as this will be the first number.

Nathan’s Cell Number #2

Following the path from the Interrogation Rooms, players will enter the Mess Hall. On the East wall, there is a wooden pinboard that has a playing card attached to it. The number on the playing card is the second number that needs to be memorized.

Nathan’s Cell Number #3

The third and final number is located in Engineering, the room close to where Juggernog can be acquired. At the back of the northeast wall, there will be a sign that says “Safety First: Days Since Last Injury” with a number written in a white box. That number is the third and final number players need.

With these numbers, players can head back to Nathan’s unit in the Bio Lab and enter the numbers in the correct order listed above to unlock the containment unit.

When players are ready, there are four valves found at the back of Nathan’s control unit, so hold the interact button on them either solo or with allies to lock yourselves into the Bio Lab and begin a boss fight. For the fight, we recommend Pack-a-Punched weapons, like the GS45, Rare (blue) rarity weapons, Deadwire, and Jugger-Nog.

Step 4: Defeat Nathan in the Bio Lab and Get the Key Card

How to Beat the Amalgam Nathan

An unlimited amount of zombies will continue to pour into the Bio Lab while Nathan also chases players down. Nathan acts like the regular Amalgam mini-boss but with more health. To defeat Nathan in Terminus, the best thing players can do is stay on the move and utilize powerful weapons like the Wonder Weapon and hard-hitting or fast-firing weapons that have been upgraded with Salvage and the Pack-a-Punch. The sole focus is to stay alive and kill Nathan, but be warned, Nathan will consume other zombies to heal himself, so try to make sure there is not an overwhelming amount of undead to prevent a path forward and to keep Nathan’s health up. Just chip away at him when he’s at a reasonable distance, as being grabbed by Nathan will nearly instantly kill players.

Step 5: Acquire the Keycard and Interact with the Communications Terminal

After Nathan has been killed, a cutscene will play, and after it, players will want to jump into the waters below the Bio Lab where they can delve deep into the water to the South West area, where a Key Card can be found below, just to the right of where Pack-a-Punch is. Players can take this Key Card to the Communications where on the top floor facing the wall will be a computer terminal with green text. Interacting with the computer will come up with a “Network Connection Error” message.

Step 6: Fix the Computer with Node Connectors to Acquire the Hacking Device

After the computer shows the “Network Connection Error” message, players are going to want to take a tactical raft and head out into the wrecked ship, located to the West of Terminus island. There is a gap in the Shipwreck to allow players to enter the bottom deck, where they can take a ladder into the Workshop. Inside the Workshop, there are some Node Connectors that can be picked up. Upon picking one of them up, a lockdown will begin, and zombies will flood the room. Drop the Node Connectors, as those carrying them cannot sprint, and prepare to kill a bunch of zombies that pour through the walls.

After killing all of the zombies that spawn during the lockdown, the ladder down to where they left their boat will be open again. Simply pick up the Node Connector and take it to the South Island, known as Crab Island. Opposite the Workbench will be a slot to place the Node Connector when facing South East. To place the Node Connector, make sure it has been picked up and then hold the interact button. If this slot has been filled, then there are two other spots.

The second location for the Node Connector is directly underneath the Sea Tower at the East pillar, so take the boat back to the main Terminus Island. Players should have two Node Connectors that they need to connect in total.

The third location to fill in the Node Connector is found on the main Terminus island, so take the boat back there and go into the Sea Caves where Speed Cola is located. Facing the West wall in this area, players will see another location to place the Node Connector. Players can return to the Guard Station where interacting with Peck will provide them with the Hacking Device from the deposit box.

Step 7: Hack the Buoys and Defuse the Bombs

How to Use the Hacking Device

To start this step, players must use the Hacking Device on the three Buoys found around Terminus Island in the Sea. Players will need to take their tactical raft out to the Sea and locate Buoys, noted by the Parasites that linger around them. At one Buoy, hold the interact button in the water and close to the Buoy to pull out the Hacking Device and wait for the hacking to complete. After hacking the first Buoy, players are now on a 2-minute time limit where they need to follow the circle of islands in an anti-clockwise fashion to find the two other Buoys. If players still have the Buoys Losing Connection timer, then it means there is an additional Buoy they missed.

Once all the Buoys have been hacked, immediately drive the boat back to the Bio Lab, as the quicker players get here, the better. After a short dialogue exchange, players will have 5 minutes to complete the Bomb Detonation step, otherwise, everyone will die and the game ends. In the Bio Lab, there are 3 bombs that must be defused, and they can be defused by holding the interact button on them for 10 to 15 seconds. This is the perfect time to use Aether Shroud or a Monkey Bomb, or even to stun zombies with the DRI-11 Beamsmasher’s alternative fire, as players must continue to interact with the bombs to deactivate them. The 15 seconds of deactivation doesn’t need to be completed in one attempt, as the progress bar saves.

Follow through the Bio Lab and look into the open windows and doors to find 2 bombs on the lower floors, and one bomb on the middle floor. It’s advised to throw Monkey Bombs before attempting to defuse, as an endless stream of zombies and mini-boss enemies will spawn to deter progress. Players only have 5 minutes to do this, so if working as a team, ensure everyone has zombie-distracting tactical equipment or weapons good enough to defend the operator defusing the bombs.

Once all three bombs have been deactivated, the Bomb Detonation timer will end, and the purple-eyed zombies will all die. At this point, players are ready for the final step: the boss fight. However, it’s essential that players jump in with the best equipment and loadout possible so don’t feel like you have to start the boss fight straight away. If you’re playing solo, you can also save and quit at this point to better prepare at a later time.

Once players are ready for the boss fight, head to the lower levels of the Bio Lab where they can interact with the slightly ajar door next to Melee Macchiato in order to enter the boss room.

Best Loadout for the Patient 13 Boss Fight

Patient 13 is quite the menace, so it’s best that players come in with the best loadout possible to beat him. Players should stock up on Essence so that they can purchase ammo if they need it, but they should also make sure that they have every Perk, but more specifically, Jugger-Nog and Quick Revive, as well as Tier 3 Armor. Weapon wise, something like the Krig C or the XM4 will do wonders, especially at the Legendary rarity and a Tier 3 Pack-a-Punch with Shadow Rift as the Ammo Mod, as Patient 13 and Amalgams are both weak to Shadow Rift.

Step 8: Defeat Patient 13, the Terminus Boss Fight

How to Beat Patient 13

Patient 13 is the Cthulhu-inspired boss fight that will take players to a hollowed square arena. There are a few things to be mindful of in this boss fight, like how exactly to damage Patient 13 and what attacks to watch out for. Zombies will always be spawning during this boss fight, and there’s a replenishing ammo crate found at the back of the arena.

The Patient 13 boss fight has three phases, with the first being its most simple. Patient 13 will use the tentacles on his back that he will slam at the front of the arena. Around the boss in the distance, there will be tentacles that fire gaseous lightning attacks. In order to damage the boss, watch for red bulbs that appear on his shoulders and shoot them with your weapons. Try to stay aware of the damage patterns to predict when to stay on the move and when to shoot. After doing enough damage, Patient 13 will submerge in the water.

To activate the second phase, players must eliminate the mini-boss zombies that have spawned in. The second phase plays similarly to the first, but now the damage spots will be in Patient 13’s mouth. Patient 13 will also use his tongue at the back of the arena, so try to avoid it when shooting for the mouth. After enough damage has been dealt, the third and final phase will begin.

For the third Patient 13 phase, he will have an electrical field around him and block off the sides of the arena. When an electric orb is being summoned by the boss, hide behind some cover and wait for it to explode. To damage the boss in the third phase, shoot at his glowing blue eyes, his mouth when he opens it, or the red bubbles that appear on his body.

After the boss dies, a cutscene will play, and then it’s all over and players have completed the Terminus Main Quest!
