Zone of the Enders

Zone of the Enders, also known as Z.O.E., is a video game that was developed and published by Konami in 2001 for the PlayStation 2. It was produced by, and is closely associated with, Hideo Kojima. The game is based around mecha combat. The mechas were designed by Yoji Shinkawa, the character and mechanical designer for the Metal Gear Solid series. The game is rated M for animated blood and animated violence, though not in such an excess that it would normally have constituted an M rating. The reason for the M rating is most likely due to its inclusion of the Metal Gear Solid 2: Sons of Liberty demo, the fourth installment of Kojima's popular stealth game.
