Released in celebration of the 20th anniversary of the hugely influential Nintendo Entertainment System console (which first appeared in Japan as the Famicom, in 1984), the "Classic NES Series" of Game Boy Advance cartridges present accurate versions of original NES games, for play on the handheld.
In Castlevania, you take the role of Simon Belmont to defeat the most terrible of vampires. You are armed with a whip, which can be upgraded from "leather," to "thorn," to "Vampire Killer" if you find the right power-ups. Throughout the seven-stage adventure, Simon confronts such horrific entities as Frankenstein, Medusa, and Death, but his true purpose comes in the final confrontation -- an all-out battle with the infamous Count Dracula.
