Around 1996, a group of graphic design and programmers working at Trinity College in Dublin, Ireland experimented with simulating real-time glass shattering. They soon formed Havok, a middleware developer who would release a soon revolutionary, self-titled physics engine suite. Havok Physics gave other developers the tools with which to add lifelike physics rendering and interaction to their video games. We're accustomed to Havok and competing alternatives today, but the mid-2000s saw a lot of fanfare around games which heavily used it. A classic example is Half-Life 2's Gravity Gun puzzles, or the ragdoll-based environmental destruction in PAIN. Other games used blended ragdoll physics for visual effect more than gameplay, such as Max Payne 2. Intel and Microsoft have owned this tech over the years, but it paved the way for PhysX and other, similar middleware of renown.

This list collects all the most noteworthy games using Havok Physics, from oldest to newest. Because there are hundreds of releases which use Havok tools, I want to focus on the standout examples which popularized the Physics middleware. This means some Source Engine titles will count (ex. Garry's Mod), but most of the non-Valve or non-commercial games likely won't qualify.

Feel free to recommend games which have Havok Physics and which you can explain the significance of in a sentence or more. I'm using MobyGames to sort through and add the initial list, but let me know if a game's misreported as having/using any Havok middleware.
