Old but still running

There's a new drug. Hylophedrine. Street name: Hype. It's addictive as shit. Streets are filled up with junkies. The city looks like a warzone. A group of friends, war veterans, has barricaded themselves inside a pub named VFW (Veterans of Foreign Wars) and try to prevent druggies who look like an army of the undead entering into the establishment. Looks like a bad slasher movie from the 80s and they most likely want it that way. Stephen Lang, Fred Williamson, William Sadler, David Patrick Kelly, George Wendt and others having a blast.
