Before Eschatos developer Qute signed a contract to make Xbox 360 games they were a homebrew WonderSwan developer. Their most popular game is, perhaps, Judgement Silversword, which eventually got a retail release. In March, you’ll be able to play it on your TV.
Eschatos, a 80s style shooter, also includes ports of Judgement Silversword (pictured) and Cardinal Sins.
Qute set 6,804 yen ($82) as the suggested retail price for Eschatos. A used copy of the hard to get Judgement Silversword tends to go for more than that on Yahoo Auctions in Japan.
