(later called Dark Wood Zone)
Act 1 wasn't finished and act 2 wasn't even made. No rings or badnicks are in act 1. The music is the same as Metropolis Zone. There's not much to say about Wood Zone. In Sonic 2 beta version C it is more complete than beta version B. If you try, you can make it from on end of the zone to the other in beta version C but not in beta version B. If you think about it, maybe Wood Zone is the past of Metropolis Zone and Metroplois Zone is the future of Wood Zone. Since Sonic 2 and Sonic CD were being made at the time, maybe Sonic 2 was going to have time travel like in Sonic CD.
