@abstractraze: Have you seen John Wick 3? Even though he has the feats in the first two movies to stomp this anyway, that makes this even harder for the Purge mercs.
I don't think so, when you have people with casual miniguns like here, which was intended to show in the second deleted video:
Not sure what the "casual" part means, but miniguns won't do anything to Wick. He can easily find cover, hit their blindspots, outmaneuver them, and cap them without them knowing. Furthermore, he has a basement to hole up in and take advantage of.
Then you have people with flamethrowers, that's just simply too much for him to handle:
Too much for him to handle? Flamethrowers have poor accuracy and a pretty limited range. He caps them before the flame reaches him.
I don't think you understand what Wick's been up against. He's fought snipers, ninjas, expert marksmen, and the world's best mercenaries, all of which have pretty insane amounts of resources at their disposal.
John Wick 3 spoilers below:
In Parabellum, he was being hunted by several thousands of people all massively more skilled and trained and able in every way than the Purge mercenaries.
At the end of the film, several dozen assassins wearing completely bulletproof armor are easily dispatched by Wick. Wick aimed for their eye-sockets and the weak points in the armor to knock them down and then killed them by moving the armor out of the way and shooting as they tried to get up.
The Purge mercenaries can't beat that. A minigun is no more useful against an individual person than an assault rifle, and Wick has faced actually skilled mercenaries with rifles without an issue. Flamethrowers require you to get close to the target, which likely won't ever happen. Furthermore, the user needs a highly flammable tank of gas to use one, meaning that they'd have to enter alone or run the risk of exploding their own teammates and only helping Wick to survive even further. They can't sneak up on him and Wick has speed fast enough to disappear right before your eyes.
While I definitely see that Wick's house might burn down and be destroyed after a few hours, but OP doesn't require him to stay in his home at all; he just starts there. Once he goes on the run, nothing will change. He just continues to decimate incoming forces. He has unlimited ammo. He can't lose this.
