The Unreal Engine has been known throughout its various iterations for pushing the limits of visual fidelity. High-definition textures, spectacular lighting, complex real-time physics, etc. You won't find any of that in the first mobile game created in Unreal Engine 4, though. What you will find is Tappy Chicken, a Flappy Bird clone.
Tappy Chicken may not be a graphical powerhouse, but it's not supposed to be. Instead, the game is intended to be an example of how easy the newest iteration of the Unreal Engine can be to program - a lesson taught earlier this year at GDC. Tappy Chicken was created by a single artist using a scripting system called Blueprints, which is part of Unreal Engine 4. Game development was started and completed within the span of just a couple of weeks.
Tappy Chicken is now available for iOS and Android devices, at the low, low cost of free. If its life story has inspired you to unleash your inner game developer, you can get Unreal Engine 4 for $19 per month.
