Once the game returns to normal speed, the machine is brought to its knees in one gigantic explosion. Quicksilver even does battle with a giant robot (let's just says it's a Sentinel) by firing dozens of rockets at the massive metal behemoth while in slow-motion. When the slow-motion effect wears off, all the bottles come crashing down on one unsuspecting victim, completely obliterating him. Quicksilver can throw multiple Molotov cocktails and have them all suspended in mid-air.
This allows for some pretty great setups. EzPlays used a 'bullet time' mod for the game to slow down combat, allowing for his Quicksilver to attack foes before they even have time to react. In this Fallout 4 video, it's because that's exactly the case. In this video, as in the movie, Quicksilver's super speed appears more like slow-motion. As in Days of Future Past, this video game version of Quicksilver puts on some tunes just before going to town on a bunch of enemies, using his super speed.
Creator EzPlays has managed to craft a Fallout 4 persona that looks nearly identical to the film version of Quicksilver, goggles and all.
