In able to successfully render the realm of Lucas Arts' upcoming Star Wars: The Force Unleashed game, three different physics engines were used. In a video we have for you, the developers talk about how Havok, Euphoria, and DMM take part in making the world of the Star Wars unlike any other game under the franchise.

Yesterday we gave you a bit of info about the upcoming LucasArts title Star Wars: Force Unleashed. Today we're bringing you more (bits of info, that is), courtesy of CVG.

Star Wars: Force Unleashed will use LucasArts' much-touted Euphoria engine, which, according to CVG, "calculates environmental damage such as smashing crates in real-time. One given example of the tech is how a tree will either break in two or splinter realistically depending on how you hit it. Likewise, steel will dent appropriately when damaged your fancy Force powers."

As previously stated, Rancors will make an in-game appearance. According to the CVG article, there's also the suggestion of players being able to control their own pack of Rancors - perfect for softening up those pesky goody-two-shoes Jedi Knights for a taste of your Force powers. Speaking of Force powers, CVG reports that many of the world-bending tricks from the popular E3 tech demo are present in Force Unleashed, including the "cannon ball"-like force push.

Of course, everyone knows how the Star Wars saga ends. LucasArts promises to shake up the lore, though, by delivering alternate endings in the game. Depending on how you play it, the bad guys really can win it all in this one. Xbox 360 and PS3 versions are being developed in-house at Lucasarts. Work on the PS2 version as well as the handheld versions for the PSP and DS have been outsourced to another still-unnamed developer. Sadly, still no details on a Wii version.
