Portal features a single, climactic boss encounter: the final confrontation with GLaDOS. Unlike traditional boss fights with health bars and attack patterns, this battle is a multi-phase puzzle that tests all the skills you've acquired throughout the game. It requires quick thinking, precise portal placement, and an understanding of GLaDOS's vulnerabilities. This section will provide a detailed strategy for defeating GLaDOS, breaking down each phase and explaining how to exploit her weaknesses. Prepare for a challenging and satisfying conclusion to your journey through the Aperture Science Enrichment Center. The key to victory lies not in brute force, but in clever application of your Portal Gun.
