It's not really true that you could jump off Phobos, at least not without tremendous effort. The escape velocity is 10-12 m/s, about as fast as Olympic 100 m sprinters go (jumping with 5 m/s straight up would take you to an altitude of 2 km though). On the other hand, the Doom guy does run at about 40 m/s ;-) Fredrik 22:19, 3 Oct 2005 (UTC)

Forward, straferunning, or wallrunning?  :>    Ryan W 23:10, 3 Oct 2005 (UTC)


I remember that I saw the original photograph of the mountains once, but it's been a few years since then and I can't find it again. Does anybody have a link to this? (I found it on a doom trivia website or something)

It's taken from this image of Yangshuo Cavern in China. - DooMAD 17:28, 10 September 2006 (UTC)
Ahh, very great! Thank you. And it's got the perfect size, perhaps I'll take it as my desktop background ;)
