Unmatched atmosphere, beautiful and immersive in both visuals and sound. For my money, better than the original in almost every way, no longer a series of disconnected puzzle rooms, but instead a single cohesive and interconnected world. On replaying, I can't help but notice the direct and clear parallel with real world colonialism - simple but effective and doesn't mess about with indirect allegories about wacky aliens or anything. A genuine work of art.
