Easy Spec OP's Save:
This save has been modified with Super Jump and Lots of Health.
You can still die but it will make everything very easy.
Go to campaign, resume game, save and quit.
Then go to spec ops and the mods will carry over.
Tips: For the last two on co-op just put the non-modded save player in the chopper or plane
and then just use the high jump ability to jump to the objective.
Took it down not working now sorry
