GameStop has just announced a new preorder bonus for Call of Duty: Advanced Warfare, that ties in directly with Destiny. If you preorder Advanced Warfare at GameStop, you will get access to a Level 20 Blacksmith Armor Shader. You have until September 21st, 2014 to preorder Advanced Warfare to get a code for this in-game Destiny item. Both Call of Duty and Destiny are published by Activision, so Activision seems to be doing a cross-game preorder promotion this year.
