Unfortunately, they seemed to opt for the method used for launching Brink - instantly turning a potentially great game into a flop via half-arsed corner cutting and lazy compromses with inadequate post-release support. Thank god there are decent modders here picking up the slack - I bought the insane edition, but I'm managing to get my money's worth thanks to the mods... if I was still playing vanilla, I'd have quit ages ago.

Japanese Tanto is unlocked in single player after you collected 6 "Letters of the Lost". It gives you double the melee power of the standard machete, so worth collecting half a dozen letters for it ;) also, just a thought, maybe the E3 weapons are the weapons used for the E3 and other conventions for the sake of game demonstrations? (just guessing)
