Secret #1

As you begin _The Siege Part 1_, follow your quest marker until you encounter a new mechanic known as the Energy Node. Use your Shield to interact with it and unlock the gate ahead. Proceed along your quest path until you reach the Battlefield.

Just before encountering your first Hell Gate, you can acquire a new weapon. To find the first secret, backtrack slightly towards the left of the first Hell Gate. Behind a Tank enemy, you’ll discover a hidden area concealed by a cascading waterfall, making it relatively easy to miss.

From the Hell Gate, follow the river to the left to reach the Tank and waterfall quickly. Here, you can also acquire a Life Sigil while being cautious of a giant tentacle enemy lurking nearby.

Secret #2 and Collectible #1

Next, from the waterfall location, head right until you observe a pillar with a blue flame atop it. In close proximity, you’ll notice a locked gate needing a Secret Key.

To find the Secret Key, turn around and climb the small hill behind you. Collect the key and use it to unlock the gate, granting you access to your second secret and your first collectible: the Toy Slayer.

Collectible #2

Your next collectible, the Toy Mancubus, is easily found on a hill underneath a massive statue. From where you found the Secret Key, jump off the cliff edge and proceed left through the enemy camp. Keep pushing forward straight ahead until you confront two Titans and a Vagary enemy. Eliminate the Vagary and smaller foes that surround it.

Afterward, continue heading straight (don’t forget to check a nearby Gold Chest on your left) until you spot the enormous statue. The Toy Mancubus collectible can be found directly beneath it.

Collectible #3

After retrieving the Toy Mancubus, glance at your map to locate a nearby Codex entry waiting for you!

Secret #3

Now, jump down from where you found the Codex, entering a marshy area. Stick close to the gates on the left side while keeping an eye out for a massive blue flag with lights beside it.

Dive into the hole beneath the flag. Swim through the hidden cave to find our third secret location, alongside some loot and a Gold Chest waiting at the end.

Once you emerge from the water, ascend the wall to your left (behind the large Tentacle enemy) and follow your quest marker to a second Hell Portal nearby. Be aware that the gate leading to the second Hell Portal will be locked until you defeat an enemy encounter just outside it.

After battling and defeating the Hell Knight inside, you’ll activate a Gore Portal that opens to the Hell Portal. Onward!

After collecting your loot, head back to the bridge and scale the wall at its end. Pull the lever at the far side of the bridge to proceed!

Secret #5

Jump down after pulling the lever to find yourself back at the entrance of the Gore Portal. As you face the newly unlocked gate, take a right toward a small pool. Dive in and swim to the opposite end while avoiding fiery jets and projectiles.

Expect enemies waiting for you on the other side, and when you reach another locked gate, look up. Sling your Shield at the green Flesh Node above to proceed!

Next, head towards the closest Gore Portal after clearing the previous cave and discovering the fifth secret location.

Captured within this area is a Leader Pinky Rider, so prioritize eliminating its surrounding minions to weaken its defenses before focusing on it. Defeating this enemy will gift you the Demonic Essence Armor Upgrade for this chapter, plus take down the third Hell Portal, leaving two more to go!

Secrets #6 and #7

Now, let’s navigate to the fourth Hell Portal on your map, one of the two remaining objectives. However, we will first stop by a cave along the way.

Inside the cave, dispose of enemies as you navigate to a blue Gore Portal that leads you to a second temple where cultists guard another Hell Portal.

To unlock the temple’s energy field, you’ll need to stand on three illuminated platforms. However, you’ll need to perform Shield Throws first!

Upon stepping into the temple, head left and use your Shield to activate the Energy Node for the next gate. Keep left once again, and interact with the terminal beside the sarcophagus.

Next, stand on the illuminated platform in the following room to expose some Hot Metal right in front of you; go ahead and throw your Shield!

Once activated, you’ll unlock the Chainshot weapon located in the center. Enemies will spawn shortly after, followed by a gate leading to the Hell Portal and the cultists managing it. Defeat them for a smoother return to the battlefield; your mission is nearly completed!

Secrets #9 and #10

Your map should display only one objective. However, there’s still one final cave to explore!

Head toward your next quest goal while hugging the left side to reach a climbable wall that will take you into the caves.

Inside the cave, dive into the water and head left to find an exit point. Shield Bash through the doorway, then Shield Throw at the Energy Node ahead to unlock the next gate.

Returning to the cave entrance, face the water and look left to spot a path that could easily be overlooked. Follow it, using your previously collected Secret Key to unlock the gate, guiding you to the tenth secret area and a new Weapon Skin!

Secret #11 and Demonic Essence Upgrade (Health)

Now you can exit the cave to advance toward your final quest objective, but before destroying the Hell Portal, challenge the Vagary hiding behind the church (refer to the map below).

Upon defeating the Vagary, another Gore Portal will spawn inside an alcove. Step inside to unlock the eleventh and final secret for this chapter!

Fire your Shield at the Energy Node located on the right side of the room. Afterward, Shield Bash into the corridor, navigating to a crate that you can remove by Shield Bashing; climb this crate, ascending the wall beside it.

Shield Bash through the next opening to find a Gold Chest. Throw your Shield at the Hot Metal that follows to return to the start of the temple.

To exit the temple, climb the crate you moved earlier and interact with the panel on the right side instead of taking the previously Shield-Bashed opening. This will unlock a gate leading back outside.

Finally, approach your quest objective to obliterate the last Hell Portal. Defeat the Mancubus in this area to receive the Demonic Essence Ammo Upgrade for this chapter, marking the conclusion of your journey through this elaborate battlefield!
