Campaign and Instant Action Worth It?

[AdrnalnJunkee]

I know you can earn badges and stuff, but it appears that I already have the unlockables from Socom3. So is it really worth doing the campaign, other than the fact that I think it is really fun?

you'll be able to use the stuff you unlock in the missions and instant action, but that aside they are just fun to do.

you can unlock the R44M & MM-1 for co-op mode. zipper might make these weapons available for classic mode, as their unlockable description says that they would work for classic
