The Sentinel introduces more complex garbage patterns and a slightly faster pace, requiring better coordination and quicker reactions from the team.

Phases & Attacks
- Phase 1 (Initial): Sends garbage in more varied patterns, sometimes creating small holes or uneven stacks.
- Phase 2 (Shielded): The Sentinel will occasionally activate a shield, making it immune to damage from line clears. During this phase, focus on clearing garbage from your own field and building your Zone meter.
- Phase 3 (Overload): After the shield drops, the Sentinel will unleash a barrage of garbage. This is a critical moment to activate Zone and clear as many lines as possible.
Strategy & Weaknesses
- Adapt to Garbage: Be prepared for more irregular garbage patterns. Practice clearing lines with holes.
- Zone Timing is Crucial: Save your Zone for when the Sentinel's shield is down and it's vulnerable, especially during its 'Overload' phase. A well-timed Zone can clear the incoming garbage and deal massive damage.
- Maintain Clean Fields: With more complex garbage, it's even more important to keep your individual playfield as clean as possible to avoid topping out.
- Weakness: Strategic Zone activation during vulnerability windows and efficient garbage clearing.
