Overwatch 2 continues to thrill players with fresh content, and Season 6 brings an exciting PvE event called Underworld. At the heart of this event is a stunning new Legendary skin for Brigitte known as Sparkplug. This cyberpunk-inspired cosmetic transforms the support hero into a gritty Omnic liberator, perfectly fitting the event’s theme of battling Null Sector forces deep in the Omnic underground. Earning it is straightforward yet challenging: finish eight specific event tasks. Whether you’re a seasoned PvE grinder or new to co-op missions, this guide breaks down everything you need to know to claim your prize before the event wraps up.
Event Overview: Diving into the Underworld
The Underworld event runs from August 10 to September 5, giving players nearly a month to tackle its demands. Your mission? Reactivate a modified TS-1 Utility Bot and use it to free oppressed Omnics from Null Sector’s grip. This isn’t just another quick play mode—it’s a full-fledged co-op story mission with branching paths, modifiers, and escalating difficulties. Success here not only nets you the Sparkplug skin but also voice lines, player icons, and heaps of XP to fuel your Battle Pass progress.
Teamwork is essential. Queue up with friends or reliable randos via the group finder. Roles matter: Tanks draw fire and protect TS-1, Damage heroes shred enemies, and Supports (including Brigitte) keep everyone healed while contributing DPS. Communication via voice or pings can turn chaotic runs into smooth victories.
All Challenges: Your Roadmap to the Skin
To snag Sparkplug, complete any eight from this list of engaging tasks. They’re divided into basic completions, role-specific feats, collectible hunts, and high-difficulty triumphs. Here’s the full breakdown in a handy table for quick reference:
| Challenge Name | Description | Difficulty |
|---|---|---|
| Basic Completion | Finish one Underworld run on any difficulty | Easy |
| Role Mastery | Complete a run as Tank, Damage, and Support | Easy-Medium |
| Bot Buddy | Keep TS-1 alive through the entire mission | Easy |
| Gratitude Protocol | Interact with TS-1 to trigger its thanks | Easy |
| Ultimate Denial | Stop A-7000 and OR Units from ulting, then win | Medium |
| Death from Above | Complete this modifier on any difficulty | Medium |
| Mystery Swap | Complete Invasion Mystery Swap modifier | Medium |
| Battery Guardians | Eliminate 4 battery thieves as a team in one run | Medium-Hard |
| Lore Hunter | Find all hidden lore interactions in a team run | Hard |
| Expert Survivor | Finish base Underworld on Expert | Hard |
| Expert Variants | Clear Death from Above and Mystery Swap on Expert | Very Hard |
| Ultimate Zones | Complete this modifier on any/Expert difficulty | Medium/Very Hard |
| Legendary Trio | Beat Underworld on Legendary with all 3 weekly modifiers | Extreme |
Pro tip: Start with the easy ones to build momentum. Many unlock progressively each week, so check your challenge tab regularly.
Step-by-Step Strategies for Tricky Challenges
Protecting TS-1 and Activating Gratitude
TS-1 is your VIP—lose it, and certain challenges fail. Stick close, use shields (Brigitte’s perfect here), and prioritize threats targeting it. For Gratitude Protocol, simply approach TS-1 and press the interact key anytime it’s nearby. A fun voice line plays, and the challenge pops instantly.
Stopping Battery Thieves (Stop, Thief!)
This one’s a fan favorite—and a pain. Four thieves spawn to nab batteries; you have two attempts per run. Pick mobile heroes like Lucio or Tracer. Save amps/boops for spawns, speed in, and burst them down. Coordinate: one spots, others collapse. On Expert, they hit harder, so burst focus is key.
Hunting Hidden Lore and Collectibles
Underworld hides interactables for lore. Key spots: near mega health packs, left wall pre-final area, around corners in tunnels. They’re glowing and pingable—team up to grab all in one go. Missing one? Restart and mark locations.
Denying Ultimates from A-7000 and OR Units
Boss phase focus: Ana (A-7000) is the real threat; OR-15 rarely ults. Dive her with stuns, sleeps, or focus fire. Brigitte’s bash and shield works wonders. Ignore adds until she’s down.
Conquering Expert and Legendary Modes
Expert amps enemy health/damage—positioning is life. Use cover, stagger spawns, and ult economically. Legendary with modifiers? Weekly rotations like Death from Above (aerial ambushes) demand anti-air comps. Practice on lower diffs first.
Tips for Efficient Challenge Grinding
- Party Composition: Brigitte (for skin flex), Lucio/Reinhardt tank line, DPS like Sojourn for peel/burst.
- Weekly Planning: Prioritize new unlocks. Aim for 4-5 challenges per session.
- Bug Workarounds: Some players hit tracking issues—restart client or report via forums.
- XP Maximizing: Pair with Battle Pass dailies for double dips.
- Solo Viability: Possible but tough; LFG Discord servers are goldmines.
Why Sparkplug is a Must-Have for Brigitte Mains
Sparkplug isn’t just pretty—it’s thematic gold. Brigitte’s kit synergizes with the Omnic rebel aesthetic: her flail becomes a sparking wrench, armor glows with neon circuits, and animations tie into TS-1 lore. Equip it in PvP for flair or PvE for immersion. As a free Legendary, it’s a rare gem in a shop-heavy game.
Community buzz on forums and YouTube raves about its detail. Pair with event icons for full drip.
Common Pitfalls and How to Avoid Them
Bugs have snagged progress (e.g., challenges not registering). Solution: Complete extras as insurance, check Overwatch forums for patches. Time crunches? Weekend queues are fastest. Don’t sleep on role challenges—quick swaps post-queue.
Future of Overwatch 2 PvE and Events
Underworld signals Blizzard’s PvE push post-Invasion. Expect more story missions, hero talents unlocking cosmetics. Sparkplug teases Brigitte’s expanding lore—watch for comics or shorts.
