shotguns and ak-47s; but really depends on the level i'm going through
enjoy the grenade launcher at times too (though it has only 1 shot per round; so again depends on the level)
the attitude of the second one appeals to me alot more too; especially the zombieland-loving aspect of me (the first feels more "zombie apocalypse, horror, how are we ever going to survive" to me; the second a bit more "oh no zombie apocalypse, but we're southerners, so we sure as hell aren't going down without a fight against these things"....or i think as one of the characters Ellis puts it, "kill all sons o' b!tches")
