The character models are similarly well detailed, and well animated to boot. Watching the Reapermen Guards running around is amusing, and the various animations of the Rippers can be quite disturbing at times.
And then there's Kabuto. Many times taller than anything else in the game, he towers over everyone else and in general looks damned awesome. It's impressive both from his viewpoint and when you simply stare at him as he mauls you with his various attacks.
Giants uses in-game cutscenes to propel the story, and they work amazingly well. The cut-scenes all have a great sense of humour, which is prevalent throughout the entire game. And with the fantastic engine that Giants uses, you won't mind the fact that the cuts are not pre-rendered FMV. They look beautiful as is.
There were a few issues with character shadows when I played Giants, but other than that the graphical glitches were far and few between. And if you have a card that does hardware texture and lighting, prepare to see reflective surfaces that'll make you grin. Any way you slice it, Giants is a pretty game.
It sounds fantastic too. The music is solid, the sound effects are good [and often humourous], and the voice acting is absolutely top-notch. The Meccs are my favourites, a bunch of cockney aliens [I said don't ask] who are simultaneously smarter and dumber than they appear. The Smarties are quite irreverent too. One of the reasons to play this game is to be immersed in its goofy sense of humour, which comes from both the graphics and the sound. If you didn't know that Planet Moon has ex-Shiny employees before, once you play the game it's rather obvious.
