Sentinels are the robotic guardians of the universe, and provoking them will lead to escalating waves of attacks. The 'boss fight' here is surviving the highest threat levels. Each wave introduces tougher units:
- Wave 1: Standard Sentinels (drones). Easy to dispatch.
- Wave 2: Sentinel Quads. More durable, faster, and have a powerful laser. Focus fire.
- Wave 3: Sentinel Walkers. Large, heavily armored mechs with powerful weapons. Target their legs first to disable movement, then their head.
- Wave 4+: Multiple Walkers, Quads, and Drones. Overwhelming numbers.
Strategy: Use cover, prioritize targets (drones first to prevent reinforcements), and use your Multi-tool's most powerful weapon (e.g., Scatter Blaster, Plasma Launcher). A Personal Forcefield is invaluable. Retreat to your ship or a base if overwhelmed. You can also flee the planet or space system to reset the threat level.
