X-Virus antidote

 is a medical item featured in the S.T.A.L.K.E.R.: Lost Alpha standalone mod.

"An antidote for X-Virus. It was developed in the X18 Labs in 1989. This is highly valuable and rare item in the Zone. It also boosts immunities during blowouts which can be very handy if you find yourself far from a shelter."

- Inventory description

X-Virus antidote

 * Exists in the game code as "antidote" in all versions and should not be confused with the later introduction of Antidote which is configured to counteract chemical burns ("booster_antchemical")
 * A drug worth a large sum of money. The description implies having a similar effect to anabiotics in Call of Pripyat, allowing the player to survive being caught in an emission.
 * Two packets are given to the player by Deedee during a first visit to his bunker (all versions)


 * v1.30013 - 1.4005:


 * Crops up as a component in many stashes, often in quantity.


 * v1.4007:


 * Still effective against Blowouts but much less available:
 * Not coded into any stashes. Effectively edited from the game in this respect.
 * Almost all Item Placements have also been removed from the board with the single remaining known example being inside the Limansk Hospital section of Damned.
 * BUGNOTE: If Deedee is visited after acquisition of this placement, he will still provide two additional copies, but the player inventory will register only two in total.
 * Workaround: Stash the free copy before talking to Deedee for the first time. Then retrieve it after he has given the other 'free' copies.

Trivia

 * Its existence may be an "Easter egg" reference to Priboi Story, another mod by Dezowave team, where it played a crucial role in the main story.
 * Anyone with the resources will pay market price for this uncommon item in early versions. Clearly, with the added availability, this may be used as an income stream.
 * The medpack reverse appears to be unclear regarding potential survival times..
