Like other consumables only found in the Nuclear Winter game mode, the stimpak and expired stimpak cannot be crafted.

The healing effects of a stimpak are canceled if the user is interrupted by taking damage. The expired stimpak heals 25% HP over 10 seconds. The standard stimpak heals 10% Hit Points over two seconds alongside 30% HP over 10 seconds, for a total of 40% HP restored. They are found exclusively in the Nuclear Winter mode.Ĭompared to the stimpaks found in Adventure mode, the Nuclear Winter variants have less potent healing effects with shorter durations. The stimpak and expired stimpak are consumables in the Fallout 76 update Nuclear Winter.
