Sonic the Hedgehog 2 HD (S2HD) is an ambitious fangame begun by a group of people who wanted to create a remake of Sonic The Hedgehog 2 with high definition (HD) graphics and remixed music while strictly preserving the original gameplay (which continues to set standards to this day). The scope of S2HD has increased since it's inception (originally intended as a straight vector redraw of the original shapes and colours), with artists and animators taking liberties with additional detail, animations, effects, and storytelling elements. S2HD then ceased production earlier that year, after one of the programmers, LOst entered a Keylogger into the game. But now, relive the magic of Sonic The Hedgehog 2 HD once again in this all new, 3rd demo! I was on the S2HD team as a developer and beta tester. We had planned to release a third demo, but never got the chance as the project shut down. Now, finally relive the third demo, rebuilt, recreated, and Keylogger free! It is still in development though, but we'll make sure to add to the Develog as soon as we can! Remember, this will hit early access soon! By the way, if you want to say "WHhen will the full game release!?" Or, "FINISH IT!! FINISH IT!!" Well, remember that it is STILL IN DEVELOPMENT, and not only that, but it is a lot of work. We are redrawing, reanimating, and rebuilding the abandoned and forgotten demo for your enjoyment once again! (P.S There's a way to get to Metropolis Zone in this version! Try figure out how!) We are proud to present the long-awaited release of Sonic 2 HD Demo 2.0. From the bottom of our hearts, we want to thank you for taking interest in the game, whether you have followed our development from the very beginning or just heard about our project today. We are truly humbled by your support!
