Challenge Event

On August 11, 2014, Project Aces announced limited-time challenge events. Similar to Ranking Tournaments, they would only occur for a few days and the rewards would not be available following the event's end; however, instead of competing with other users to get the most points, players only have to complete a specific challenge to earn a reward. To earn all of the event's rewards, challenges must be completed one after the other in a specific order.

November 2014
A challenge event has been confirmed for November 2014, to be conducted from November 7, 3 AM GMT through November 17, 8 AM GMT. This event showcases the same Typhoon Rot Team skin as well as the same Ace Combat: Assault Horizon Legacy emblems from the first Challenge Event, to celebrate the announcement of Ace Combat 3D: Cross Rumble +. However, the event also features four new aircraft skins, one of which is the F/A-18F Super Hornet "Grun Team" skin as well as their emblem.

Unlike the first Challenge Event, some challenges are immediately available, and they are not separated by "difficulty". Completing some challenges will unlock other ones.

August 2014
From August 13, 2014 at 3 AM GMT to August 19, 2014 at 8 AM GMT, the first Challenge Event took place, featuring a Typhoon skin from Rot Team as well as emblems from the Lancer, Beast, Cocoon and Albireo Squadrons.

The challenges were separated into three sets: Beginner, Intermediate, and Expert. Within each set, completing one 1.x challenge would unlock the 2.1 challenge, while completing two 1.x challenges would unlock the 2.1, 2.2, and 2.3 challenges. These rules apply to all other tiers (i.e. completing one 2.x challenge unlocks 3.1, while completing any two 2.x challenges unlocks 3.1, 3.2, and 3.3). Completing three challenges in one tier has no bearing on unlocking any extra challenges within that set's next tier.

Exclusive to the event, challenges with a time limit are locked from being re-attempted if the player fails to complete it in the time limit. This occurs with the standard challenges in the game as well, but unlike those, the challenges in the event do not have a cooldown period allowing the player to re-attempt the challenge the next day. Therefore, if a player suspects they will not be able to complete a challenge in the time limit, they should cancel it before the time runs out to ensure that they can still complete it another time.

All gold-colored challenges contain the featured rewards for this event. All red-colored challenges feature a time limit and will be locked to the player if they don't finish it in time.
