If you are losing consistently, you are doing something wrong...
Presumably you are playing on the easier difficulty, Greenhorn mode?
I'd advise you to watch some video playthroughs to pick up some strategies. I posted a few videos myself, but others have done so too.
Or, if you can think about a particularly difficult encounter you had to face, please post me the setup (what day it is, which baddies appeared, which gearlocs you had and which skills you trained) and I'll give you an outline of what you could have done differently!
The one major thing I was doing wrong was having to choose between healing or attempting to unlock one of the trove loots. In every recovery phase, every gearloc gets to make one lockpicking attempt.
This was the rule correction that consistently let me start to do really well in the game, whereas before a lot more luck was involved.
