Name This Video Game?

Its a vague recollection, hopefully you can help.

Its an old one, I remember there being two separate modes (or it may have been one of those old demo discs you'd get in Playstation Magazines) where one you'd be in a car speeding through a city, in the bottom left corner there was a timer, and when it would hit zero you could see and hear an explosion which would wipe out the city and kill you. Graphics were similar;slightly to Carmageddon

The other mode (or other game) would start of very Time Crisis-esque...first person shooting, duck and cover, shoot and progress. I THINK it was the first mission and I THINK it was in an airport and outside before you went in you'd have to kill a few people, and I vaguely remember a helicopter too......

Thanks in advance, who ever answers first gets best answer
