The standard offer is instant beta access and 10 percent off, with some unlockables to go

Defense Grid 2, the sequel to probably the best-looking tower defense game in the world, is now open for business on Steam, with pre-orders available for those who can't wait until the game comes out this fall.

Developer Hidden Path Entertainment is attempting to put more twists into the standard "give us your money sooner, get some guaranteed bonuses" formula, in the form of three different reward tiers, that get unlocked progressively, based on the total number of pre-orders placed.

This means that the promotion is following the old adage "the more, the merrier," as whenever a tier threshold is cleared, the content is offered to everyone who placed a pre-order.

The first tier has already been smashed through, consisting of the Containment expansion of Defense Grid: The Awakening, as well as a digital art book.

The second tier includes the tier one rewards and adds a 50 percent off coupon for Windborne, the company's sandbox adventure currently available on Early Access.

The third tier will net pre-order customers A Matter of Endurance, an "original audio story" created by Mary Robinette Kowal, scheduled to arrive on Defense Grid 2's launch.

In addition to this, everyone gets 10 percent off Defense Grid 2's final retail price, as well as immediate access to the game's beta, with every placed pre-order.

Defense Grid 2 is coming out this September, for the Microsoft Windows, Mac, Linux, Xbox One and PlayStation 4 platforms.
