Borderlands 4: Timid Kyle’s Neglected Opening walkthrough
The Timid Kyle’s Neglected Opening offers both heavy combat and traversal challenges in Borderlands 4. Inside, you will encounter Threshers who give decent XP farming options.
Step-by-step direction

- Minecart rails: On entering the mine, head east following the minecart rails. This will lead you deeper into the mine.

- Stone pillars: Inside, you’ll find a chamber full of stone pillars. Locate and break through the black and red plank barrier on the northern side of the cavern.

- Waterfall and the chasm: You’ll eventually find yourself near a waterfall with a massive gap. Cross the gap by climbing nearby rocks.

- Climbing up: When you reach the stairs, go up and take the ladder and jump across the broken bridge. Take the path thats straight ahead of you.

- Alter room: Look for an altar-like structure in this area and find the hidden passage behind it. Break through the planks to gain access to the hidden passage.

- Locating the boss arena: During the final stretch of the dungeon, you’ll need to navigate through twisting passages and cross chasms using the grappling hook. Just follow the path until you can see the vending machines (Ammunition, Meds, and Moxxi’s Encore). The boss arena is just beyond the vending machines.
Tip: Load up with ammo and meds, since Voraxis is a gigantic, tanky boss.

Voraxis boss fight guide

The boss at the end of Timid Kyle’s Neglected Opening is Voraxis, a gigantic version of the Wyrm Thresher. The fight can easily get overwhelming with the amount of mobs that Voraxis spawns.
Moveset
- Fireball Barrage: Voraxis launches fireballs that explode on impact. Strafe away to avoid splash damage.
- Burrow charge: Voraxis will occasionally dive underground and charge toward you. It’s easy to avoid if you keep track of the dirt trail.
- Spinning charge: Voraxis will sometimes charge you in a quick spiral motion; you’ll need to have swift reflexes to avoid these attacks.
- Summoned Threshers: Voraxis will summon Wyrm Threshers to aid him; if left unchecked, they can quickly overwhelm you.
