Crytek undoubtedly developed Crysis with the most believable physics engine to date. Such statement is easy to make after watching this user-made video of a thousand nuclear barrels that exploded to form an enormous cloud.

No, we're not kidding. It is funny how the player survived being just several feet away from what easily could have finished Master Chief's fight early, but the spectacular explosion is breathtaking.

Keep in mind that what you'll see below is rendered in real-time, and according to the person who posted the video, took an Intel Core 2 Quad Q6600 CPU, 2 GB of RAM, and just a mid-end Nvidia GeForce 8600GS video card. Crytek keeps on saying that Crysis works fine on slightly dated machines, and it is indeed proven here.
