Assembler games forum member got his hands on an XBOX 1 devkit. A lot of unreleased games were unearthed, including “SONIC EXTREME”. SONIC EXTREME looks like Sonic Team’s attempt at Tony Hawk… quite literally! You can see Sonic doing Tony Hawk style skateboard tricks.
So yeah… just think. We could have had a Sonic game like this! This was an amusing video to watch and I just had to share it with you guys!
