Comparing to the Space Marines and Eldar, Orks have 5 level tiers in the game so their tier upgrades will be the same as the tech level. Not to mention some of their upgrades are also from the past WH40K games and the description is in ork language. Neat isn't it? Okay, the elder is the last race to be in the last chapter for the update to come...
