Rainbow Six Siege has its place. It’s an energetic, imaginative multiplayer FPS with some smart mechanics and a good mix of arcade pace and simulation-style gravitas. It’s a solid online shooter - but it’s not Rainbow Six, not in the real, classic sense. Rainbow Six is slow, tense, and your life is balanced on a knife edge. It almost feels like a survival horror game, something close to tank-control legends like Silent Hill and Resident Evil. Rainbow Six Vegas was maybe the last R6 game in that original mold. But the best one, for me, remains Rainbow Six 3, and now 21 years later, it’s all yours for less than $3.
