The fully configurable Skirmish Booster Pack allows you to choose every element of PvE gameplay, from resources, teams, and victory conditions to opponent civilizations, difficulty, and strategy.
There are a large number of options and settings that can be configured in the Skirmish Booster. For all of the settings other than victory condition, players can also choose a random option that makes the battles even more chaotic and exciting.
The Skirmish Booster allows access to all of your civilization's units even if you haven't unlocked them in the tech tree through the campaign. You also have access to all of the ages, even if you haven't reached the appropriate city level and unlocked them via the tech tree. You do not, however, get access to all technologies; these still need to be unlocked by spending points you receive for leveling. Experience earned from the Skirmish Booster can be used to level, fully unlocking units and technologies, and improve the rewards.
Speaking of rewards, the greater the challenge, the bigger they get. In addition to being rewarded at the end of each successful match, there will be several global quests that allow you to earn unique advisors, vanity trophies, and additional experience, coin, and chests.
