New publisher Lexicon, which recently signed up Bad Day LA for European release, has announced a time-bending DS side-scroller called Chronos Twins.
As you can see from the screenshots, Chrono Twins uses a weird split-screen engine that allows you to control past and present versions of your 2D character in the same location.
Other details are a bit hard to come by - although everyone's keen to note that it has nothing to do with Square's Chrono Trigger series - but with the game due out in Q1 2007 (priced £24.99, Lexicon notes), expect more announcements in the near future.
Meanwhile, Lexicon says it's in final discussions to sign up four other DS titles. More on that when they announce.
