Plus I got the vehicle hacks which are reminiscent of those of Watch Dogs 2. Cool stuff to take control over them, blow them up etc.
It's kind of funny to use floor it when they're in front of or taking cover behind vehicles.
Yeah loot is pretty screwed up as a result of the changes. You still find MaxDocs and Bounce Backs in crates a lot, and grenades, but this doesn't do anything since they're aren't accumulated items anymore.
I don't think this is quite right, you can craft grenades with the appropriate schematics or buy them at weapon shops, but I don't think you can craft inhalers (or if you can, I haven't found any recipes for it yet) and I haven't seen them for sale either. I think they made the inhalers and grenades somewhat common in certain areas as loot is so you get the variety and tier upgrades since they don't upgrade automatically, but they will once you've acquired the next tier.
So for instance, if you have a tier 1 frag grenade and loot tier 2 frag grenade, your frag grenade will become tier 2 whether or not you have it equipped, but you won't get an additional "item" for it. If you have a tier 2 frag grenade and loot a tier 2 frag grenade, you won't see any changes. They probably oversaturated the PL area with this stuff to ensure you have a base level of gear for the DLC.
n.b. I haven't started any PL content yet, just basing this on what I've seen in the revised base game.
