Done by a modder, NOT by Crytek.
Modder ‘gametime’ has managed to recreate that Konami office room, proving that Crytek’s proprietary engine can compete with Konami’s next-gen engine. As gametime revealed, all of that assets that have been used have a proxy model and the level is in real scale. Many assets have POM to further enhance their realism. Oh, and contrary to Konami’s recreation… this CryEngine 3 office is being shown off at a HD resolution.
