As you understood, your damages are doubled. But remember that some monsters have also is ability. That makes the game very hard to play in Nightmare mode. Some of them can now kill you in only one shot. Here are some advices :


My first new idea was the new realistic shotgun feature. It fires two shells at once, and each shell must be reloaded one by one. It makes it very powerful, but for an heavy reload time price. Also remember that you can not fire until the reload of the current shell was completed, making you again vulnerable.

With this weapon, most of the monsters can be killed with only one head shot. But its shell consumption makes it unusable all along the game.

To resume, this weapon can be used by the very high end players who always make head shot and manage the reload time and shell consumption.
