Triumph Studios' excellent (but flawed) Overlord will receive a sequel on Xbox 360, PS3 and PC, along with new versions for the Wii and DS, all scheduled for 2009. IGN reports Overlord II will have smarter minions who can ride mounts, use war machines and sail ships. The scope of the game world has been broadened in the sequel and the controls for the Pikmin-style gameplay have been "greatly improved." We loved the first game, and it's great to hear about all these improvements for the sequel, but we hope "polish" is a word that Triumph doesn't forget this time around.
The Overlord franchise will also spawn Overlord Dark Legend on Wii by Climax Studios, an "all new game" penned by Rhianna Pratchett. The game seems to be set in the original Overlord's world with many of the same characters, but with the inclusion of some fractured fairy tale aspect. Finally, on DS (and also by Climax Studios), Overlord Minion will present players with a puzzle action game. OK, does that about cover all the Overlord info? Good, all hail the Overlord!
