Phase 1: General Strategy

   • Use double jumps to reach higher platforms for cover.
   • Duck under her energy beams to minimize damage.
2. Best Weapons to Use

Phase 2: Attack Patterns and Counters

• Energy Shots & Grenades
  • Jump over or strafe to the side.
  • Avoid going for health pickups unless absolutely necessary.
• Shockwave Spikes
  • When she slams the ground, immediately jump onto a pedestal.
  • As soon as she finishes, jump off to avoid the follow-up energy waves.
• Laser Barrage
  • Use pedestals for cover, but don’t rely on them too much.
  • Keep moving in wide circles to avoid damage.
• BFG Ammo Spawns
  • A single BFG shot can momentarily stun her.
  • Use it only when necessary, as it won’t finish the fight instantly.

   • Avoid unnecessary risks—survival is key.
   • Use glory kills to replenish resources when possible.
3. Final Moments
