Max Payne Wiki

Valkyr Junkies are those unfortunate enough to have become addicted to valkyr. Max Payne comes across many of them in poor neighborhoods of New York City during his 2001 vendetta.

Although armed, generally, the junkies just lie on the ground talking to themselves in a crazed stupor and do not attack Payne. If they are caught in a crossfire, though, they do start shooting, all the while laughing and screaming in a macabre manner.

Junkies are known to be surprisingly tough enemies. This most likely stems from them being under the effect of valkyr, the drug which greatly increases human strength.
