For those that are finding the game harder in solo - are you using your 'V' button to renew your armor kit? You should be able to use it 3x I think - unless you have upgraded how many armor kits you can carry.
Also - if you are using them and still having troubles...you might consider getting the drone that repairs armor as well.
