Techland announced today that Steam users can pre-purchase Dying Light in a 4-pack bundle. The bundle goes for the price of three games, and players get a fourth copy free. So the player that purchases will get one copy for them, and then three extra copies as gifts for their friends.
In the latest gameplay trailer, the Invasions by the Night Hunter (the asymmetric multiplayer aspect of the game) was revealed. You can watch the video below. The mode lets the player take control of the Night Hunter and invade the games of other players, allowing you to upgrade your skills as well. It is part of the Be the Zombie DLC, and comes with every copy of the Dying Light 4-pack.
In addition, pre-purchasing Dying Light on Steam gives every pre-purchased copy an exclusive in-game weapon, the Punk Queen.
Dying Light releases on January 27, 2015.
