Centipede for the Dreamcast is a curious title for a couple of reasons. It's part of what is, for all intents and purposes, a sort of trilogy of retro reboots that includes two other properties with roots in the very early days of gaming - Q*bert and Frogger. While there are several retro collections for the Dreamcast in the form of Namco Museum, Sega Smash Pack, Yu Suzuki Game Works, Atari Anniversary Edition, Midway's Greatest Arcade Hits 1 & 2 and Jimmy White's 2: Cueball, none of these titles feature complete re-imaginings of the classic titles contained therein.
No, Centipede, Q*bert and Frogger are unique in that they introduce updated visuals, new modes and - most notably in the case of Centipede - totally new gameplay mechanics. Interestingly, all three of these titles come from the Hasbro Interactive/Atari mash-up that was borne out of the acquisition of the latter by the former, however for the sake of this being 'a quick look at...' we're only going to focus on the most radically redesigned of the three - Centipede.
Released in 2000 by Hasbro Interactive masquerading as Atari and developed by Leaping Lizard Software, Centipede is a modern take on the classic game of the same name that was released to much critical and commercial success back in 1980. Having only been born in 1982, I don't actually remember the initial arcade release of Centipede, but over the years I've played plenty of variations on the formula and I'm sure you have too. Naturally, coming from an era when hardware was less graphically capable than what we have today, Centipede featured basic visuals but had one very simple premise that was replicated in many titles of the period - shoot the enemies, get a high score...and survive the onslaught.
