The Season Pass grants players a 30% discount on all cash shop items for six months. The Season Pass itself is reported to set players back a hefty $99.99, so it will likely only be useful for the most hardcore of Age of Empires Online players.

In addition to the Season Pass, Microsoft also announced that players who buy the Greek and Egyptian civilizations will receive the Defense of Crete booster for free.
