Collecting data cells will unlock weapons at the Weapons Testing Ground. Don't worry if you miss a few, as you can use Mission Select to find the data cells you missed. It lists how many are left in each mission. The game automatically saves after you have picked up a cell, so there is no need to complete entire levels. Click here for Fracture achievement guide.
