1.) What the cheat does and how to do it: This isn't really a cheat, rather an unlockable. You get a cutscene featuring Vergil if you complete this task. You must kill 100 demons during the credits. The last Demon is a Hell Vanguard, so make sure you're quick with the other demons. You cannot go Devil Trigger in the credits, which makes this even more difficult. The highest amount of kills I've gotten is 103 with Agni & Rudra being the only Devil Arm I used. Also, don't rely on Lady to kill many demons. She uses guns, and like all guns in the game they don't hurt demons much. It just will knock them to the ground. I suggest you extensively practice your combos before this. Because you need to take out about 4 demons per second or so. Also, I've only been able to accomplish this in Swordmaster mode. There are no walls to run up or anything of the such so Trickster fails here. You don't have time to rack up rage to attack with Royal Guard, guns don't hurt demons enough so don't use Gunslinger, Quicksilver is only good when you can use Devil Trigger with it, and I'm not sure if you can summon an ally with Doppleganger. And even if you can, without swordmaster special skills, it's very difficult.
2.) Game name: Devil May Cry 3: Dante's Awakening
3.) Console(s) the code works for: Ps2
4.) Any special requirements to get it to work (ex.: at a certain part of the game, 50% complete, etc.) You do this during the credits, so you must beat the game for this to work. Heh, good luck with that, unless you're playing the easier special edition. [For those who are unaware of which version you have, Devil May Cry 3: Dante's Awakening is extremely hard. You'll know if you're playing this. Special edition is a version rereleased for the 90% of gamers who bought the original DMC3 and could not beat it due to it's intense difficulty. Vergil is a selectable character in this version of the game and Jester is an extra boss. I don't know if anything differs with Special Edition during the credits fight, as I only own three and I'm one of the few, the proud, the gamers who beat the original DMC3 whee . Also, I'm currently trying to beat the game in Heaven and Hell mode to see if the One-Hit Game over rule applies in the credits fight. Quite frankly, defeating Vergil [second time] without being touched once is quite difficult. When I finally finish this mode, I'll report in about whether you die after one hit in credits as in the game itself.]
