Of course, you wouldn't know any of that unless you read it somewhere(well, it is in the manual), such as on-line, because the game makes less than any attempt at telling you(but hey, at least the story does make the whole deal with being able to resurrect(the game lets you have extra lives, the way FPSs that went before it did) make sense and able to be explained within the context of it). This takes place in The Lost Land, a different dimension in which all the stuff the developers thought up and didn't want to abandon could co-exist, and you must fight your way through many enemies, to finally rescue the world. I only found out about the comic book(and have not read it) after completing the game, but I understand that they have little to do with each other.
