Feature creep suggestion. =P
Perhaps, if you like it, for inclusion after all the main features have been put in and are being tested.
An option on game start to play with an additional option of Scavenger Mode.
If selected, the game slightly increases the Surveillance requirements for finding loot and slightly increases the Bypass requirements for claiming it.
Not excessively, just enough for it to make a difference.
Currently I think the loot is about right. Once there are more things to buy and more variety in what loot can be found, it will be awesome.
To slightly reduce the amount of end-mission loot will make a marked difference in overall profitability.
