challenge Mode

[Red XIII]

Ok.
Im no n00b but i rarely play multiplayer and even more rarely do i play challenge mode
i was playin with a m8 the other day and was bombarded with questions about whats the point in this and what do we get out of it and what are the terms of getting weapons etc. i found my self confused and lied but i want to set it straight and find out how challenge mode works.
so any 1 wanna clear things up for me?

u have to beat c mode completly but if u do it offline it is a big waste of time the weapons suck

online you get to choose an s-rank weapon if i you get under 7 hours (i think) but offline, like masterofchaos said, its pretty pointless unless you want the weapons for their looks

i sorta want a crazy tune,...*cries* for looks
