Did you find it hard at all to get? Just got it myself after trying for about 40 min. I started with getting times just above 53 seconds and the last 30 laps of trying to get it my times were 52.15-52.10. My final time was 51.66.
Probably not that impressive but this is the first wipeout game that I put some real time into.
The 11th round is where games are won, heroes are made, and mvps are earned. Socom fan for life.
