Yes, only Zone Zeus left for the 100%. I'm stuck in Zone 74 unfortunately, I hope to get it one day with the time. Most of the time I'm in the online enjoying a few races so I've not tried it well with the enough time, but I hope to have the oportunity in summer since now I'm a bit busy in my job and in the university.
If you don't mind me taking a bit of your time to give you a short explain: to be honest, this was one of my biggest challenge in mind when talking about beating a game since the first week I was playing it. This is my first WipEout unfortunately, because I wanted to play the other ones in the past but I couldn't, I just played the original one in 1995 for a few hours. So... at the beginning I wasn't even sure to be able of doing a thing like this... without the experience of the other WipEout before I was thinking I couldn't reach the needed handling for a so skill-based game. With the time and much passion for the game (I always had love for the WipEout design, concept, music, ambient and so on) I started to feel I was not only learning more or less how to pilot in WipEout but also enjoying it like a kid while listening to a special music score I applyed to it focused on instrumental trance melodies that speed-up the BPMs of my heart. I consider WipEout HD the hardest Playstation 3 title when talking about trophies (others says there's also a 2nd one: Warhawk) but at the same time the Playstation 3 game with the highest price/quality relation anybody can find (and more after I saw it did get a discount for a limited time months ago). I highly suggest everybody who love this game, to not give up, because it's worth every time you spend on it.
There are amazing players out there, believe me. I've been shocked many times of the results of players I do know in the online modes. I'm just a normal pilot who tries to enjoy the WipEout universe as much as possible. I would be very pleased to drive with anybody from here in the skies, so I hope to see you there too mate
