If you literally asked the third-person shooter Without Warning to justify itself, it might rave enthusiastically about its unique storyline, which follows six protagonists over twelve hours of terrorist-foiling shenanigans. It might continue by pointing out that it’s nothing at all like the TV series 24... but that would be a lie.
In practice, the only real difference between this and 24 is that you don’t necessarily play the scenes in chronological order. Time jumps back and forth, just like in the film Pulp Fiction, as you guide the six different characters through a plot which pieces itself together before your eyes. It’s like Tetris with guns. But only in the most abstract, tangential of senses, so really it’s not like Tetris at all. After all, Tetris doesn't have a plot and Without Warning does, even though that plot sucks. Which we guess makes two differences between this and 24.
