NEW in ver 1.2:
1. Added totally unbalanced Super Stimpak. Enjoy.

Short version: This stimpak mod applies penalties 1.5x your healing to your hydration, sleep (sleep might be 2x) and food stats. This is the first alpha, so is probably balanced like Charlie Sheen is balanced.

Tested it out, and it's incredible. Makes your needs real frigging scary sometimes, and makes gunfights much more intense, because even if you outlive your foes, are you gonna make it?

Requirements: FNV
Conflicts: None detected and I'm running a batshit crazy stack of mods with this little Esp at the bottom of my load order.
Problems: Did not find SuperStim in my searches, but was eager just to test. This will need redo and can be seen as a 'cheat' item currently. Healing powder untouched, not sure what I want to do with it. Probably leave it vanilla or reduce its effectiveness greatly.

On my mind:
1. Super Stimpaks
2. Healing powder
3. Hydra

Can you guys, hardcore and not, download this bad boy and give it a whirl? I really want to hear feedback. NonHC players: I'm just curious if it has a negative impact on the reg stimpaks for you guys. That was literally my first time hitting 'save' after any GECK edits and it's possibly a pig's breakfast. It worked right out of the box for me, but don't know what the mileage will be for you other folk.

Philosophy: (tl;dr version)
Playing HC mode is a frigging breeze. Food, water and sleep become minor annoyances, not deciding factors of fate, as they should be in an irradiated wasteland populated by crazies. Obviously, the Courier is stronger than other wastelanders and should be able to provide himself a modicum of comfort, even luxury; he's a bit of a badass.

But badasses, like gods, bleed.

And blood is made out of iron, plasma, and protein. And the hole he's bleeding out of, or the laceration, needs to be filled in with complex cellular structures that the miraculous stimpak allows him to build on the fly, including fat, muscle, skin, sometimes even bone.

Normally, a nonfatal gunshot wound leaves someone recuperating for months. The stim somehow bypasses this and lets you heal up in about six seconds. Six seconds! Miracles!

In civilized times, this let little Johnny get right back onto the field after a crippling craniospinal injury was sustained. Good, hot, American meals would pep him right back up after the 'little doctor' had done its work.

In the Courier's time, he would've found himself wasting away at the powerful metabolic effects stitching his flesh back together after the repeated abuses he subjected himself to. He'd be madly searching through anywhere with four walls for anything edible he could use to hold himself over, to keep from collapsing. He wouldn't step out of his lavishly modded player home with the five bottles of water and five brahmin steaks requisite for some good trail breakfasts. He would take extra, or he would kill it on the way.

My First Impression: I conquered the GECK and modded this last night while finishing NVB1. I fought the Judge and got seriously worked. I ended up pumping the stimpak hotkey. The included images show the result.
I was scrounging through his bunker for food and picking dog steaks up off the floor, drinking sarsparilla and generally being a little disgusting in the aftermath. And I was still in trouble. Not like 'Gosh, my agility is down 1. That's hardly even noticeable but bugs me!' More like, 'F***, I could starve.'
After that I decided to walk to Camp McCarran. Big Horner herds became prey, the Coyote Den was bombed and cut up for food, and I'm still dealing with H2O penalties. Even the lamest of roadside robber was approached with caution, lest a crit hit require another stim be injected.
In short, it was awesome.
