Yeah, Zealot's the hardest. Hardcore is, basically, Normal mode with zero checkpoints and you can only use 3 saves. So, in Hardcore, enemy strength is that of Normal difficulty but the overall lack of ammo drops is that of Zealot difficulty.
There are some cool workarounds that you can use to make both Zealot and Hardcore somewhat easier, but they require the DLC. For instance, get to a Store. Now buy both DLC Detonator weapons. Fire off all 6 rounds of detonator mines and, for each, deactivate each. Sell the guns back to the Store and purchase the guns again (at zero credits). Now repeat where you fire/deactivate the weapon's ammo. Once you have a big pile of deactivate mines sitting there, go pick them all up and sell them at the Store. You can get 2,000 credits for every 10 mines you sell. You can do this at every Store, so if you find yourself in a jam while in Zealot or Hardcore, you can use this to either quickly stock up on health and ammo OR you can spend several hours doing this to rack up a good supply of Power Nodes (cost is 10,000 credits each) to upgrade your RIG and weapons. It's a very handy trick, especially since you can start doing this at the very end of Chapter 1.
