You could have these items exist but I can't see carrying both types at the same time. Wait, scratch that. I COULD see it happening but Survivors that do that would be slowed down as if they are limping even though they are in the healthy threshold. I also think that these upgraded versions of the medkit, pills, and shots should be even more rare to find as if they are experimental or in a test series. On Expert, I'd imagine that there is only one Large Medkit throughout the entire campaign if any at all. Maybe another added effect on the Large Medkit could be that it can keep you up an additonal down instead of three incaps and you're dead. Giga adrenaline shot, for its duration, is over-powered. To balance it, I would have its duration reduced everytime an Infected manages to hit you, down to a minimal of the original Adrenaline Shot duration. Also, while under the effects of the Giga Adrenaline Shot, Special Infected that deal damage against the Survivor that has used a Giga Adrenaline Shot recently hit twice as hard. Example would be that when the Smoker's tongue squeezes a Survivor on Expert, it would deal 60 damage per squeeze instead of 30 damage per squeeze. Common Infected damage would be 40 in front, 20 at the back. The Charger would deal 30 damage on his punch, 10 damage on an impact charge, and 30 damage per pummel. Hunter would deal 50 damage per scratch and would kill in about 4.5 seconds on Expert when pounced on someone. On lower difficulties, the Witch would be able to one-shot a Survivor boosted by Giga Adrenaline... if the Witch can catch up to the Survivor that is. Depending on distance gone from taking the shot to when the shot wears off, provided that no damage was taken to reduce the duration, the Survivor will be slowed down by moving so far very quickly and it will take the same duration as the shot to regain their energy. I'll come up with more balances later. I don't see any particular issue with Mega Pills but I would suggest a cooldown on it to prevent an "overdose" on Mega Pills. Maybe only one chug of Mega Pills per map or campaign and it cancels the use of normal Pills. However Adrenaline Shots can still be used.
