Most people love Hideo Kojima for his Metal Gear Solid series, but it's easy to forget that he created a whole other game series about battling robots called Zone of the Enders. People who do remember playing Zone of the Enders and Zone of the Enders: The 2nd Runner have been calling for an HD collection since HD collections starting appearing on store shelves.
It was announced a while back that the Zone of the Enders HD collection was coming, but no definitive release date was announced. Unforfunately, we still don't have a definitive release date. What we do know is that the game will be coming out sometime this fall. As you may expect, it'll be releasing for PS3 and Xbox 360 and featuring updated HD graphics which should make it look completely awesome.
If you've never played the Zone of the Enders games, you'll definitely want to pick this up and give it a try. If you played the first because you purchased it just to get the Metal Gear Solid 2 demo, you will want to grab this for the second game anyway, which is widely considered the better of the two.
