I have this long-going project called ZonoS. It's a game I'm building in Unreal. The thing about this game is that it's designed to be built like games would have been made in the non-3d days. The inspiration is Space Harrier - one of my favourite arcade games of all time. The cool part with this is that there's no forward movement. It's all faked perspective and UV tricks.
Pretty much everything is WIP. And sorry for the terrible compression, i'll replace this video soon.
