Square Enix Licenses Unreal Engine 3 and Unreal Engine 4

Epic Games Japan, which is providing local support, worked directly with Square Enix on the new license
Epic Games has announced an agreement with Square Enix granting Square Enix a group-wide license to develop multiple games with Epic's Unreal Engine 3 and its Unreal Engine 4 technology. This sweeping agreement will supplement Square Enix's proprietary software and ensure the studio is armed with the most powerful game development tools and technologies available across all major platforms.
Both iOS and Android versions of Demons' Score, developed by iNiS and published by Square Enix, were created with Unreal Engine 3.
