The sudden switch from playing a hybrid of COPS and GTA in True Crime: Streets of LA to fighting a radioactive lava dragon in what looked like the Earth's core.
That should have been cool, but, unlike in Condemned 1 where the build up to fighting demons is slow and intense and psychological and makes you wonder if what's his name (I think it's Ethan) is just slowly losing his mind the same way that the addicts have done, True Crime: Streets of LA just throws you into this fight with no warning and no sense of transition. I have never seen a more out of left field plot twist. Giant Space Flea From Nowhere, much?
