Pre-order it for yourself and for three of your co-op buddies.
Now that Techland can’t make another zombie co-op action game like they did with Dead Island (because Deep Silver owns that IP, and Deep Silver has other plans), they’ve just gone ahead and made it anyway, except they call call it Dying Light, and it will be published by Warner Bros. Still, if you fancy some four player co-op zombie action, then you’re in luck as Dying Light is now available to pre-order on Steam.
What is more, not only can you buy the game just for yourself, you can also straight up buy a Four Pack– this will include four copies of the game (presumably for you to gift or sell the other three to your co-op buddies) being sold at a bundled, discounted price that is lower than it would be if you bought all four copies at once.
Even better, this deal includes all pre-order bonuses as well. Really, it’s probably the best way to pre-order the game, assuming you know what to do with the other three codes.
