Laos blind off one mission just go on to shutdown fly to the third tower your 10 min from the end you get 50.000. Plus emblem
Nooby question, but LASO is all skulls on and not dying, right?
And how can you just skip the first two towers?
There is a gap on the third tower you can land and jet pack through a hole-if you die press save and no you don’t need blind
Alright 
And you can do it co-op I guess? 50 000 xp sounds delicious…
Yes but if one of you get shot you all go back to your last check point
