Boss 3: The Sentinel
  1. Attack Phase 1 (Multi-Lane & Slides): The boss will create tracks that split into multiple lanes, requiring quick lane changes and wall slides to hit targets and collect gems.
  2. Attack Phase 2 (Advanced Ground Pounds): Expect rapid ground pound sequences, sometimes immediately followed by turns or hits.
  3. Weak Point Exposure: After a complex sequence, the boss's core will glow. Deliver a final hit.
  4. Defensive Shield: The Sentinel might temporarily activate a shield, requiring you to hit specific glowing segments around it to break its defense before you can attack its core.
  5. Counter-Attack: The boss sends out dense waves of projectiles, sometimes requiring you to weave through gaps or hit specific ones.

Strategy:

  • Fluid Lane Changes: Practice rapid and precise lane switching. You'll often need to switch lanes to hit targets or avoid obstacles.
  • Break Shields: When the boss shields itself, quickly identify and hit the glowing segments to expose its core.
  • Anticipate Complex Sequences: The Sentinel throws everything at you. Stay focused and anticipate rapid transitions between different mechanics.

Rewards:

Defeating The Sentinel unlocks Level 4 and a significant score bonus.
