Over a decade later, SWAT 4 is still the pinnacle of tactical shooters. No other shooter has even come close to the feeling of storming buildings and arresting perps like SWAT 4. Shooters like this, which actually place consequence on your actions and provide you choice in how you approach situations, are a lost art. SWAT doesn't hold your hand -- you can shoot your commanding officer in the face and fail the training mission 5 seconds in. It doesn't place arbitrary limits on you. And, crucially, it gives you ways to interact with both enemies and innocents beyond just shooting them. And that's something you are not gonna see in a lot of games from this decade.
