The miniatures game by Mongoose came out in 2005, and struggled through a new edition in 2007, only to stall soon.
Never played it, but the reception wasn't very good. The game was you-go-i-go, with some minimal capability for response, which was increased in the 2nd ed. I guess every second game out there does this equally well or better. The focus was on small-scale action, like so many other games. So no massive/epic battles, as in the film. And yet no single-man destruction strikes as in the original Heinlein book. A somewhat bland average, with just the typical units you would except.
Some of the figures were liked, especially the Arachnids. You can sometimes see them still fetching a passable price on eBay. Many ordinary troops, like humans and especially the 'Skinnies' were esteemed poor sculpts, only worthy as cheap alternatives to GW or other sci-fi games.
