Spider-Man Web of Shadows

Well this pretty much an obvious achievement but what you do here is during the game you will collect XP by defeating enemies, completing bonus goals, completeing missions and just overall stopping crimes. As you progress through the missions you will have an opportunity to upgrade after missions or by pressing start and right trigger will take you to the upgrade screen, in order to get this achievement you must 100% the red and black costumes so just buy everything, you should get somewhere between half and two thirds done with Act 3. Hope this helps and keep gettin achievements
