Mars, smuggle. Move 6 crates about 2 miles through a narrow tunnel. After moving 3, inspection time, NONSTOP respawning giant wyverns, about 8 at either end of the tunnel, as soon as you kill 1 another spawns, as soon as you pick up a crate & take any damage you drop it & it goes back to its spawn. Even when I managed to get 1 thru the tunnel theres 8 wyverns blocking the exit & ooops damage, crate disappears back to 2 miles back in its spawn. Took about 10 mins to realise this simply isn't possible, & the other 2 guys already timed out - so just unplugged the consoles & logged off.
Miserable.
The whole game is miserable - wtf happened bungie - there's no fun here, only darkness.
Just play it on Expert (200) level and all fine.
I am 550 and did many on GM and majority, not all, successful.
But man is it tedious and unfun.
Until I realised that for normal faction orders I need to complete 3 on Expert level (33% count) and I need to run 3 anyway for the priority order of my current faction.
Hence everything on GM level but smuggling where curiously I see a lot of 550ies running Expert as well.
Easy on Expert.
